 187-280 1.00e-61

FERM domain C-lobe of Protein 4.1 family; The protein 4.1 family includes four well-defined members: erythroid protein 4.1 (4.1R), the best known and characterized member, 4.1G (general), 4.1N (neuronal), and 4.1 B (brain). The less well understood 4.1O/FRMD3 is not a true member of this family and is not included in this hierarchy. Besides three highly conserved domains, FERM, SAB (spectrin and actin binding domain) and CTD (C-terminal domain), the proteins from this family contain several unique domains: U1, U2 and U3. FERM domains like other members of the FERM domain superfamily have a cloverleaf architecture with three distinct lobes: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. The brain is a particularly rich source of protein 4.1 isoforms. The various 4.1R, 4.1G, 4.1N, and 4.1B mRNAs are all expressed in distinct patterns within the brain. It is likely that 4.1 proteins play important functional roles in the brain including motor coordination and spatial learning, postmitotic differentiation, and synaptic architecture and function. In addition they are found in nonerythroid, nonneuronal cells where they may play a general structural role in nuclear architecture and/or may interact with splicing factors. The FERM C domain is the third structural domain within the FERM domain. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs) , the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

 530-637 1.25e-46

4.1 protein C-terminal domain (CTD); At the C-terminus of all known 4.1 proteins is a sequence domain unique to these proteins, known as the C-terminal domain (CTD). Mammalian CTDs are associated with a growing number of protein-protein interactions, although such activities have yet to be associated with invertebrate CTDs. Mammalian CTDs are generally defined by sequence alignment as encoded by exons 18-21. Comparison of known vertebrate 4.1 proteins with invertebrate 4.1 proteins indicates that mammalian 4.1 exon 19 represents a vertebrate adaptation that extends the sequence of the CTD with a Ser/Thr-rich sequence. The CTD was first described as a 22/24-kDa domain by chymotryptic digestion of erythrocyte 4.1 (4.1R). CTD is thought to represent an independent folding structure which has gained function since the divergence of vertebrates from invertebrates.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in erythrocyte membrane protein band 4.1 (EPB41) and similar proteins; EPB41, also termed protein 4.1 (P4.1), or 4.1R, or Band 4.1, or EPB4.1, belongs to the skeletal protein 4.1 family that is involved in cellular processes such as cell adhesion, migration and signaling. EPB41 is a widely expressed cytoskeletal phosphoprotein that stabilizes the spectrin-actin cytoskeleton and anchors the cytoskeleton to the cell membrane. EPB41 contains a FERM domain, a spectrin and actin binding (SAB) domain, and a C-terminal domain. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

 187-280 1.00e-61

FERM domain C-lobe of Protein 4.1 family; The protein 4.1 family includes four well-defined members: erythroid protein 4.1 (4.1R), the best known and characterized member, 4.1G (general), 4.1N (neuronal), and 4.1 B (brain). The less well understood 4.1O/FRMD3 is not a true member of this family and is not included in this hierarchy. Besides three highly conserved domains, FERM, SAB (spectrin and actin binding domain) and CTD (C-terminal domain), the proteins from this family contain several unique domains: U1, U2 and U3. FERM domains like other members of the FERM domain superfamily have a cloverleaf architecture with three distinct lobes: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. The brain is a particularly rich source of protein 4.1 isoforms. The various 4.1R, 4.1G, 4.1N, and 4.1B mRNAs are all expressed in distinct patterns within the brain. It is likely that 4.1 proteins play important functional roles in the brain including motor coordination and spatial learning, postmitotic differentiation, and synaptic architecture and function. In addition they are found in nonerythroid, nonneuronal cells where they may play a general structural role in nuclear architecture and/or may interact with splicing factors. The FERM C domain is the third structural domain within the FERM domain. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs) , the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in erythrocyte membrane protein band 4.1 (EPB41) and similar proteins; EPB41, also termed protein 4.1 (P4.1), or 4.1R, or Band 4.1, or EPB4.1, belongs to the skeletal protein 4.1 family that is involved in cellular processes such as cell adhesion, migration and signaling. EPB41 is a widely expressed cytoskeletal phosphoprotein that stabilizes the spectrin-actin cytoskeleton and anchors the cytoskeleton to the cell membrane. EPB41 contains a FERM domain, a spectrin and actin binding (SAB) domain, and a C-terminal domain. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

 530-637 1.25e-46

4.1 protein C-terminal domain (CTD); At the C-terminus of all known 4.1 proteins is a sequence domain unique to these proteins, known as the C-terminal domain (CTD). Mammalian CTDs are associated with a growing number of protein-protein interactions, although such activities have yet to be associated with invertebrate CTDs. Mammalian CTDs are generally defined by sequence alignment as encoded by exons 18-21. Comparison of known vertebrate 4.1 proteins with invertebrate 4.1 proteins indicates that mammalian 4.1 exon 19 represents a vertebrate adaptation that extends the sequence of the CTD with a Ser/Thr-rich sequence. The CTD was first described as a 22/24-kDa domain by chymotryptic digestion of erythrocyte 4.1 (4.1R). CTD is thought to represent an independent folding structure which has gained function since the divergence of vertebrates from invertebrates.

 186-280 5.67e-43

FERM domain C-lobe of Protein tyrosine phosphatase non-receptor proteins 3 and 4 (PTPN4 and PTPN3); PTPN4 (also called PTPMEG, protein tyrosine phosphatase, megakaryocyte) is a cytoplasmic protein-tyrosine phosphatase (PTP) thought to play a role in cerebellar function. PTPMEG-knockout mice have impaired memory formation and cerebellar long-term depression. PTPN3/PTPH1 is a membrane-associated PTP that is implicated in regulating tyrosine phosphorylation of growth factor receptors, p97 VCP (valosin-containing protein, or Cdc48 in Saccharomyces cerevisiae), and HBV (Hepatitis B Virus) gene expression; it is mutated in a subset of colon cancers. PTPMEG and PTPN3/PTPH1 contains a N-terminal FERM domain, a middle PDZ domain, and a C-terminal phosphatase domain. PTP1/Tyrosine-protein phosphatase 1 from nematodes and a FERM_C repeat 1 from Tetraodon nigroviridis are also included in this cd. The FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe within the FERM domain is part of the PH domain family. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs) , the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in erythrocyte membrane protein band 4.1-like protein 1 (EPB41L1) and similar proteins; EPB41L1, also termed neuronal protein 4.1 (4.1N), belongs to the skeletal protein 4.1 family that is involved in cellular processes such as cell adhesion, migration and signaling. It is a cytoskeleton-associated protein that may serve as a tumor suppressor in solid tumors. It suppresses hypoxia-induced epithelial-mesenchymal transition in epithelial ovarian cancer (EOC) cells. The down-regulation of EPB41L1 expression is a critical step for non-small cell lung cancer (NSCLC) development. Moreover, EPB41L1 functions as a linker protein between inositol 1,4,5-trisphosphate receptor type1 (IP3R1) and actin filaments in neurons. EPB41L1 contains a FERM domain, a spectrin and actin binding (SAB) domain, and a C-terminal domain. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

 179-298 2.61e-33

FERM domain C-lobe of FERM, RhoGEF and pleckstrin domain-containing protein 1 and related proteins; Members here include FARP1 (also called Chondrocyte-derived ezrin-like protein; PH domain-containing family C member 2), FARP2 (also called FIR/FERM domain including RhoGEF; FGD1-related Cdc42-GEF/FRG), and FRMD7(FERM domain containing 7). FARP1 and FARP2 are members of the Dbl family guanine nucleotide exchange factors (GEFs) which are upstream positive regulators of Rho GTPases. FARP1 has increased expression in differentiated chondrocytes. FARP2 is thought to regulate neurite remodeling by mediating the signaling pathways from membrane proteins to Rac. It is found in brain, lung, and testis, as well as embryonic hippocampal and cortical neurons. These members are composed of a N-terminal FERM domain, a proline-rich (PR) domain, Dbl-homology (DH), and two C-terminal PH domains. Other members in this family do not contain the DH domains such as the Human FERM domain containing protein 7 and Caenorhabditis elegans CFRM3, both of which have unknown functions. They contain an N-terminal FERM domain, a PH domain, followed by a FA (FERM adjacent) domain. The FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs), the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in FERM, RhoGEF and pleckstrin domain-containing protein 1 (FARP1) and similar proteins; This family includes the F1 sub-domain of FERM, RhoGEF and pleckstrin domain-containing proteins FARP1, FARP2, and FERM domain-containing protein 7 (FRMD7). FARP1, also termed chondrocyte-derived ezrin-like protein (CDEP), or pleckstrin homology (PH) domain-containing family C member 2 (PLEKHC2), is a neuronal activator of the RhoA GTPase. It promotes outgrowth of developing motor neuron dendrites. It also regulates excitatory synapse formation and morphology, as well as activates the GTPase Rac1 to promote F-actin assembly. FARP2, also termed FERM domain including RhoGEF (FIR), or Pleckstrin homology (PH) domain-containing family C member 3, is a Dbl-family guanine nucleotide exchange factor (GEF) that activates Rac1 or Cdc42 in response to upstream signals, suggesting roles in regulating processes such as neuronal axon guidance and bone homeostasis. It is also a key molecule involved in the response of neuronal growth cones to class-3 semaphorins. FRMD7 plays an important role in neuronal development and is involved in the regulation of F-actin, neurofilament, and microtubule dynamics. All family members contain a FERM domain that is made up of three sub-domains, F1, F2, and F3. This family corresponds to F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

FERM domain C-lobe of Novel band 4.1-like protein 4 and 5 (NBL4 and 5); NBL4 (also called Erythrocyte protein band 4.1-like 4; Epb4 1l4) plays a role the beta-catenin/Tcf signaling pathway and is thought to be involved in establishing the cell polarity or proliferation. NBL4 may be also involved in adhesion, in cell motility and/or in cell-to-cell communication. No role for NBL5 has been proposed to date. Both NBL4 and NBL5 contain a N-terminal FERM domain which has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe is a member of the PH superfamily. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs) , the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in erythrocyte membrane protein band 4.1-like 5 (EPB41L5); EPB41L5 is a mesenchymal-specific protein that is an integral component of the ARF6-based pathway. It is normally induced during epithelial-mesenchymal transition (EMT) by an EMT-related transcriptional factor, ZEB1, which drives ARF6-based invasion, metastasis and drug resistance. EPB41L5 also binds to paxillin to enhance integrin/paxillin association, and thus promotes focal adhesion dynamics. Moreover, EPB41L5 acts as a substrate for the E3 ubiquitin ligase Mind bomb 1 (Mib1), which is essential for activation of Notch signaling. EPB41L5 is a member of the band 4.1/Nbl4 (novel band 4.1-like protein 4) group of the FERM protein superfamily. It contains a FERM domain that is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in tyrosine-protein phosphatase non-receptor type 4 (PTPN4); PTPN4, also termed protein-tyrosine phosphatase MEG1 (MEG) or PTPase-MEG1, belongs to the non-transmembrane FERM-containing protein-tyrosine phosphatase (PTP) subfamily characterized by a conserved N-terminal FERM domain, a PDZ domain, and a C-terminal PTP catalytic domain. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N). PTPN4 protects cells against apoptosis. It associates with the mitogen-activated protein kinase p38gamma (also known as MAPK12) to form a PTPN4-p38gamma complex that promotes cellular signaling, preventing cell death induction. It also inhibits tyrosine phosphorylation and subsequent cytoplasm translocation of TRIF-related adaptor molecule (TRAM, also known as TICAM2), resulting in the disturbance of TRAM-TRIF interaction. Moreover, PTPN4 negatively regulates cell proliferation and motility through dephosphorylation of CrkI.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in E3 ubiquitin-protein ligase MYLIP and similar proteins; MYLIP, also termed inducible degrader of the LDL-receptor (Idol), or myosin regulatory light chain interacting protein (MIR), is an E3 ubiquitin-protein ligase that mediates ubiquitination and subsequent proteasomal degradation of myosin regulatory light chain (MRLC), LDLR, VLDLR and LRP8. Its activity depends on E2 ubiquitin-conjugating enzymes of the UBE2D family, including UBE2D1, UBE2D2, UBE2D3, and UBE2D4. MYLIP stimulates clathrin-independent endocytosis and acts as a sterol-dependent inhibitor of cellular cholesterol uptake by binding directly to the cytoplasmic tail of the LDLR and promoting its ubiquitination via the UBE2D1/E1 complex. The ubiquitinated LDLR then enters the multivesicular body (MVB) protein-sorting pathway and is shuttled to the lysosome for degradation. Moreover, MYLIP has been identified as a novel ERM-like protein that affects cytoskeleton interactions regulating cell motility, such as neurite outgrowth. The ERM proteins includes ezrin, radixin, and moesin, which are cytoskeletal effector proteins linking actin to membrane-bound proteins at the cell surface. MYLIP contains a FERM-domain and a C-terminal C3HC4-type RING-HC finger. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

 187-280 3.48e-13

FERM domain C-lobe of Protein tyrosine phosphatase non-receptor proteins 14 and 21 (PTPN14 and 21); This CD contains PTP members: pez/PTPN14 and PTPN21. A number of mutations in Pez have been shown to be associated with breast and colorectal cancer. The PTPN protein family belong to larger family of PTPs. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. The members are composed of a N-terminal FERM domain and a C-terminal PTP catalytic domain. The FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. Like most other ERM members they have a phosphoinositide-binding site in their FERM domain. The FERM C domain is the third structural domain within the FERM domain. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs) , the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

 187-279 3.86e-13

FERM domain C-lobe of E3 ubiquitin ligase myosin regulatory light chain-interacting protein (MYLIP; also called inducible degrader of the LDL receptor, IDOL); MYLIP/IDOL is a regulator of the LDL receptor (LDLR) pathway via the nuclear receptor liver X receptor (LXR). In response to cellular cholesterol loading, the activation of LXR leads to the induction of MYLIP expression. MYLIP stimulates ubiquitination of the LDLR on its cytoplasmic tail, directing its degradation. The LXR-MYLIP-LDLR pathway provides a complementary pathway to sterol regulatory element-binding proteins for the feedback inhibition of cholesterol uptake. MYLIP has an N-terminal FERM domain and in some cases a C-terminal RING domain. The FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in tyrosine-protein phosphatase non-receptor type 3 (PTPN3); PTPN3, also termed protein-tyrosine phosphatase H1 (PTP-H1), belongs to the non-transmembrane FERM-containing protein-tyrosine phosphatase (PTP) subfamily characterized by a conserved N-terminal FERM domain, a PDZ domain, and a C-terminal PTP catalytic domain. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N). PTPN3 associates with the mitogen-activated protein kinase p38gamma (also known as MAPK12) to form a PTPN3-p38gamma complex that promotes Ras-induced oncogenesis. It may also act as a tumor suppressor in lung cancer through its modulation of epidermal growth factor receptor (EGFR) signaling. Moreover, PTPN3 shows sensitizing effect to anti-estrogens. It dephosphorylates the tyrosine kinase EGFR, disrupts its interaction with the nuclear estrogen receptor, and increases breast cancer sensitivity to small molecule tyrosine kinase inhibitors (TKIs). It also cooperates with vitamin D receptor to stimulate breast cancer growth through their mutual stabilization.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in tyrosine-protein phosphatase non-receptors PTPN14, PTPN21, and similar proteins; This family includes tyrosine-protein phosphatase non-receptors PTPN14 and PTPN21, both of which are protein-tyrosine phosphatase (PTP). They belong to the FERM family of PTPs characterized by a conserved N-terminal FERM domain and a C-terminal PTP catalytic domain with an intervening sequence containing an acidic region and a putative SH3 domain-binding sequence. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N). PTPN14 plays a role in the nucleus during cell proliferation. PTPN21 interacts with a Tec tyrosine kinase family member, the epithelial and endothelial tyrosine kinase (Etk, also known as Bmx), modulates Stat3 activation, and plays a role in the regulation of cell growth and differentiation.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in the ERM family proteins; The ezrin-radixin-moesin (ERM) family includes a group of closely related cytoskeletal proteins that play an essential role in microvilli formation, T-cell activation, and tumor metastasis through providing a regulated linkage between F-actin and membrane-associated proteins. These proteins may also function in signaling cascades that regulate the assembly of actin stress fibers. The ERM proteins consist of an N-terminal FERM domain, a coiled-coil (CC) domain and a C-terminal tail segment (C-tail) containing a well-defined actin-binding motif. They exist in two states, a dormant state in which the FERM domain binds to its own C-terminal tail and thereby precludes binding of some partner proteins, and an activated state, in which the FERM domain binds to one of many membrane binding proteins and the C-terminal tail binds to F-actin. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N). Merlin, which is highly related to the members of the ezrin, radixin, and moesin (ERM) protein family that are directly attached to and functionally linked with NHE1, is included in this family.

 186-241 8.03e-07

FERM domain C-lobe/F3 of the ERM family; The ERM family includes ezrin, radixin, moesin and merlin. They are composed of a N-terminal FERM (ERM) domain (also called N-ERMAD (N-terminal ERM association domain)), a coiled coil region (CRR), and a C-terminal domain CERMAD (C-terminal ERM association domain) which has an F-actin-binding site (ABD). Two actin-binding sites have been identified in the middle and N-terminal domains. Merlin is structurally similar to the ERM proteins, but instead of an actin-binding domain (ABD), it contains a C-terminal domain (CTD), just like the proteins from the 4.1 family. Activated ezrin, radixin and moesin are thought to be involved in the linking of actin filaments to CD43, CD44, ICAM1-3 cell adhesion molecules, various membrane channels and receptors, such as the Na+/H+ exchanger-3 (NHE3), cystic fibrosis transmembrane conductance regulator (CFTR), and the beta2-adrenergic receptor. The ERM proteins exist in two states, a dormant state in which the FERM domain binds to its own C-terminal tail and thereby precludes binding of some partner proteins, and an activated state, in which the FERM domain binds to one of many membrane binding proteins and the C-terminal tail binds to F-actin. The FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain of ERM is part of the PH domain family. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs), the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in Ezrin and similar proteins; Ezrin, also termed cytovillin, or villin-2, or p81, is a member of the ezrin/radixin/moesin (ERM) family of cytoskeletal proteins that plays an essential role in microvilli formation, T-cell activation, and tumor metastasis through providing a regulated linkage between F-actin and membrane-associated proteins. These proteins may also function in signaling cascades that regulate the assembly of actin stress fibers. The ERM proteins consist of an N-terminal FERM domain, a coiled-coil (CC) domain and a C-terminal tail segment (C-tail) containing a well-defined actin-binding motif. The C-terminal domain can fold back to bind to the FERM domain forming an autoinhibited conformation. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N). Ezrin is a tyrosine kinase substrate that functions as a cross-linker between actin cytoskeleton and plasma membrane. It has been implicated in the regulation of the proliferation, apoptosis, adhesion, invasion, metastasis and angiogenesis of cancer cells.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in tyrosine-protein phosphatase non-receptor type 14 (PTPN14) and similar proteins; PTPN14, also termed protein-tyrosine phosphatase pez, or PTPD2, or PTP36, is a widely expressed non-transmembrane cytosolic protein tyrosine phosphatase (PTP). It belongs to the FERM family of PTPs characterized by a conserved N-terminal FERM domain and a C-terminal PTP catalytic domain with an intervening sequence containing an acidic region and a putative SH3 domain-binding sequence. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N). PTPN14 plays a role in the nucleus during cell proliferation. It forms a complex with Kibra and LATS1 proteins and negatively regulates the key Hippo pathway protein Yes-associated protein (YAP) oncogenic function by controlling its localization. It specifically regulates p130 Crk-associated substrate (p130Cas) phosphorylation at tyrosine residue 128 (Y128) in colorectal cancer (CRC) cells. Moreover, PTPN14 may be a critical enzyme in regulating endothelial cell function. It plays a crucial role in organogenesis by inducing transforming growth factor beta (TGFbeta) and epithelial-mesenchymal transition (EMT). It also acts as a modifier of angiogenesis and hereditary haemorrhagic telangiectasia. It regulates the lymphatic function and choanal development through the interaction with the vascular endothelial growth factor receptor 3 (VEGFR3), a receptor tyrosine kinase essential for lymphangiogenesis. Furthermore, PTPN14 functions as a regulator of cell motility through its action on cell-cell adhesion. Beta-Catenin, a central component of adherens junctions, has been identified as a PTPN14 substrate. PTPN14 works as a novel sperm-motility biomarker and a potential mitochondrial protein.

 202-277 2.44e-06

FERM domain C-lobe of Protein tyrosine phosphatase non-receptor 13 (PTPH13); There are many functions of PTPN13 (also called PTPL1, PTP-BAS, hPTP1E, FAP1, or PTPL1). Mice lacking PTPN13 activity have abnormal regulation of signal transducer and activator of transcription signaling in their T cells, mild impairment of motor nerve repair, and a significant reduction in the growth of retinal glia cultures. It also plays a role in adipocyte differentiation. PTPN13 contains a kinase non-catalytic C-lobe domain (KIND), a FERM domain with two potential phosphatidylinositol 4,5-biphosphate [PtdIns(4,5)P2]-binding motifs, 5 PDZ domains, and a carboxy-terminal catalytic domain. There is an nteraction between the FERM domain of PTPL1 and PtdIns(4,5)P2 which is thought to regulate the membrane localization of PTPN13. PDZ are protein/protein interaction domains so there is the potential for numerous partners that can actively participate in the regulation of its phosphatase activity or can permit direct or indirect recruitment of tyrosine phosphorylated PTPL1 substrates. The FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs), the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in FERM domain-containing protein 4A (FRMD4A); FRMD4A is a cytohesin adaptor involved in cell structure, transport and signaling. It promotes the growth of cancer cells in tongue, head and neck squamous cell carcinomas. It also regulates tau secretion by activating cytohesin-Arf6 signaling through connecting cytohesin family Arf6-specific guanine-nucleotide exchange factors (GEFs) and Par-3 at primordial adherens junctions during epithelial polarization. As a genetic risk factor for late-onset Alzheimer's disease (AD), FRMD4A may play a role in amyloidogenic and tau-related pathways in AD. FRMD4A contains a FERM domain that is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in tyrosine-protein phosphatase non-receptor type 21 (PTPN21) and similar proteins; PTPN21, also termed protein-tyrosine phosphatase D1 (PTPD1), is a cytosolic non-receptor protein-tyrosine phosphatase (PTP) that belongs to the FERM family of PTPs characterized by a conserved N-terminal FERM domain and a C-terminal PTP catalytic domain with an intervening sequence containing an acidic region and a putative SH3 domain-binding sequence. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N). PTPN21 interacts with a Tec tyrosine kinase family member, the epithelial and endothelial tyrosine kinase (Etk, also known as Bmx), modulates Stat3 activation, and plays a role in the regulation of cell growth and differentiation. It also associates with and activates Src tyrosine kinase, and directs epidermal growth factor (EGF)/Src signaling to the nucleus through activating ERK1/2- and Elk1-dependent gene transcription. PTPD1-Src complex interacts a protein kinase A-anchoring protein AKAP121 to forms a PTPD1-Src-AKAP121 complex, which is required for efficient maintenance of mitochondrial membrane potential and ATP oxidative synthesis. As a novel component of the endocytic pathway, PTPN21 supports EGF receptor stability and mitogenic signaling in bladder cancer cells. Moreover, PTPD1 regulates focal adhesion kinase (FAK) autophosphorylation and cell migration through modulating Src-FAK signaling at adhesion sites.

 10-81 2.31e-05

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in merlin and similar proteins; Merlin, also termed moesin-ezrin-radixin-like protein, or neurofibromin-2 (NF2), or Schwannomerlin, or Schwannomin, is a member of the ezrin/radixin/moesin (ERM) family of cytoskeletal proteins that plays an essential role in microvilli formation, T-cell activation, and tumor metastasis through providing a regulated linkage between F-actin and membrane-associated proteins. These proteins may also function in signaling cascades that regulate the assembly of actin stress fibers. The ERM proteins consist of an N-terminal FERM domain, a coiled-coil (CC) domain and a C-terminal tail segment (C-tail) containing a well-defined actin-binding motif, merlin however lacks the typical actin-binding motif in the C-tail. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N). Merlin plays vital roles in controlling proper development of organ sizes by specifically binding to a large number of target proteins localized both in cytoplasm and nuclei. Merlin may function as a tumor suppressor that functions upstream of the core Hippo pathway kinases Lats1/2 (Wts in Drosophila) and Mst1/2 (Hpo in Drosophila), as well as the nuclear E3 ubiquitin ligase DDB1-and-Cullin 4-associated Factor 1 (DCAF1)-associated cullin 4-Roc1 ligase, CRL4(DCAF1). Merlin may also has a tumor suppressor function in melanoma cells, the inhibition of the proto-oncogenic Na(+)/H(+) exchanger isoform 1 (NHE1) activity.

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in the ERM family proteins, Ezrin, Radixin, and Moesin; The ezrin-radixin-moesin (ERM) family includes a group of closely related cytoskeletal proteins that plays an essential role in microvilli formation, T-cell activation, and tumor metastasis through providing a regulated linkage between F-actin and membrane-associated proteins. These proteins may also function in signaling cascades that regulate the assembly of actin stress fibers. The ERM proteins consist of an N-terminal FERM domain, a coiled-coil (CC) domain and a C-terminal tail segment (C-tail) containing a well-defined actin-binding motif. They exist in two states, a dormant state in which the FERM domain binds to its own C-terminal tail and thereby precludes binding of some partner proteins, and an activated state, in which the FERM domain binds to one of many membrane binding proteins and the C-terminal tail binds to F-actin. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N).

 187-277 1.82e-04

FERM domain C-lobe of FERM domain containing 1 and 6 proteins; FRMD6 (also called willin and hEx/human expanded) is localized throughout the cytoplasm or along the plasma membrane. The Drosophilla protein Ex is a regulator of the Hippo/SWH (Sav/Wts/Hpo) signaling pathway, a signaling pathway that plays a pivotal role in organ size control and is tumor suppression by restricting proliferation and promoting apoptosis. Surprisingly, hEx is thought to function independently of the Hippo pathway. Instead it is hypothesized that hEx inhibits progression through the S phase of the cell cycle by upregulating p21(Cip1) and downregulating Cyclin A. It is also implicated in the progression of Alzheimer disease. Not much is known about FRMD1 to date. Both FRMD1 and FRMD6 contains a single FERM domain which has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe is a member of the PH superfamily. The FERM domain is found in the cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs) , the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites.

 10-81 3.08e-04

FERM (Four.1 protein, Ezrin, Radixin, Moesin) domain, F1 sub-domain, found in radixin and similar proteins; Radixin is a member of the ezrin/radixin/moesin (ERM) family of cytoskeletal proteins that plays an essential role in microvilli formation, T-cell activation, and tumor metastasis through providing a regulated linkage between F-actin and membrane-associated proteins. These proteins may also function in signaling cascades that regulate the assembly of actin stress fibers. The ERM proteins consist of an N-terminal FERM domain, a coiled-coil (CC) domain and a C-terminal tail segment (C-tail) containing a well-defined actin-binding motif. The C-terminal domain can fold back to bind to the FERM domain forming an autoinhibited conformation. The FERM domain is made up of three sub-domains, F1, F2, and F3. This family corresponds to the F1 sub-domain, which is also called the N-terminal ubiquitin-like structural domain of the FERM domain (FERM_N). Radixin plays important roles in cell polarity, cell motility, invasion and tumor progression. It mediates the binding of F-actin to the plasma membrane after a conformational activation through Akt2-dependent phosphorylation at Thr564. It is also involved in reversal learning and short-term memory by regulating synaptic GABAA receptor density.
