Ras-associating (RA) domain of Ras-association domain family 5 (RASSF5); RASSF5, also called New ras effector 1 (NORE1), or regulator for cell adhesion and polarization enriched in lymphoid tissues (RAPL), is a member of a family of six related RASSF1-6 proteins (the classical RASSF proteins) and is expressed as three transcripts (A-C) via differential promoter usage and alternative splicing. All transcripts variants of RASSF5 contain the RA or SARAH domains. The RA domain of the classical RASSF proteins has a beta-grasp ubiquitin-like fold with low sequence similarity to ubiquitin. The RA domain mediates interactions with Ras and other small GTPases, and the SARAH domain mediates protein-protein interactions crucial in the pathways that induce cell cycle arrest and apoptosis. RASSF5A is a pro-apoptotic Ras effector and functions as a Ras regulated tumor suppressor. RASSF5C is regulated by Ras related protein and modulates cellular adhesion.

Novel Ras effector 1 C-terminal SARAH (Sav/Rassf/Hpo) domain; The Nore1-SARAH, C-terminal, domain of Nore1, the tumour-suppressor, a novel Ras effector, has a characteriztic coiled-coil structure. It is a small helical module that is important in signal-transduction networks. The recombinant SARAH domain of Nore1 crystallizes as an anti-parallel homodimer with representative characteriztics of coiled coils. The central function of the SARAH domain seems to be the mediation of homo- and hetero-oligomerization between SARAH domain-containing proteins. Nore1 forms homo- and hetero complexes through its C-terminal SARAH (Sav/Rassf/Hpo) domain.

protein kinase C conserved region 1 (C1 domain) found in the Ras association domain-containing protein 1 (RASSF1)-like family; The RASSF1-like family includes RASSF1 and RASSF5. RASSF1 and RASSF5 are members of a family of RAS effectors, of which there are currently 8 members (RASSF1-8), all containing a Ras-association (RA) domain of the Ral-GDS/AF6 type. RASSF1 has eight transcripts (A-H) arising from alternative splicing and differential promoter usage. RASSF1A and 1C are the most extensively studied RASSF1; both are localized to microtubules and involved in the regulation of growth and migration. RASSF1 is a potential tumor suppressor that is required for death receptor-dependent apoptosis. RASSF5, also called new ras effector 1 (NORE1), or regulator for cell adhesion and polarization enriched in lymphoid tissues (RAPL), is expressed as three transcripts (A-C) via differential promoter usage and alternative splicing. RASSF5A is a pro-apoptotic Ras effector and functions as a Ras regulated tumor suppressor. RASSF5C is regulated by Ras related protein and modulates cellular adhesion.

C-terminal SARAH domain found in scaffold protein salvador (Sav), Ras-association domain proteins, and mammalian STE20-like protein kinases (MST); The SARAH (Salvador-RassF-Hippo) domain family includes scaffold protein salvador (Sav), Ras-association domain proteins (RASSF1-6), and mammalian STE20-like protein kinase (MST) subfamily members (MST1-2 and Hippo). Sav is a scaffold protein mainly found in metazoans. Drosophila melanogaster Sav, also called Shar-pei (SHRP), promotes both cell cycle exit and apoptosis in Drosophila. It plays a key role in the Hippo/SWH (Sav/Wts/Hpo) signaling pathway. Human protein salvador homolog 1, also called 45 kDa WW domain protein (WW45), acts as a mammalian sterile 20-like kinase 1 (MST1)-binding protein required to enhance MST1-mediated apoptosis. It is a regulator of STK3/MST2 and STK4/MST1 in the Hippo signaling pathway. Classical RASSF proteins interact either directly or indirectly with activated Ras. Ras proteins are small GTPases that are involved in cellular signal transduction. They seem to modulate some of the growth inhibitory responses mediated by Ras and may serve as tumor suppressor genes. RASSF1-6 contains a conserved SARAH motif adjacent to the RA domain that functions in scaffolding and regulatory interactions. MST1/2 and Hippo are involved in a conserved pathway that governs cell contact inhibition, organ size control, and tumor development. MST1 and MST2 are STE20 family stress-activated, pro-apoptotic serine/threonine-protein kinases which, following caspase-cleavage, enter the nucleus and induces chromatin condensation followed by internucleosomal DNA fragmentation. They are key components of the Hippo signaling pathway which plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. Hippo (Hpo), also called STE20-like kinase MST (dMST), is the Drosophila homolog of STE20-like protein kinases, MST1 and MST2. It is a STE20 family serine/threonine-protein kinase that functions as a tumor suppressor by restricting cell proliferation and promotes apoptosis in conjunction with salvador and warts. Hpo also plays a key role in the Hippo/SWH signaling pathway. This model corresponds to the C-terminal SARAH domain, a characteristic coiled-coil structure. It is a small helical module that is important in signal-transduction networks. The central function of the SARAH domain seems to be the mediation of homo- and heterodimerization between SARAH domain-containing proteins.

It mediates activation of STK3/MST2 and STK4/MST1 during Fas-induced apoptosis by preventing their dephosphorylation. RASSF1 has eight transcripts (A-H) arising from alternative splicing and differential promoter usage. RASSF1A and 1C are the most extensively studied RASSF1, with both localized to microtubules and involved in regulation of growth and migration. With the exception of some minor splice variants (RASSF1F and RASSF1G), RASSF1 contains an RA domain and a C-terminal SARAH (Salvador-RassF-Hippo) protein-protein interaction motif. The RA domain of the classical RASSF proteins has a beta-grasp ubiquitin-like fold with low sequence similarity to ubiquitin. The RA domain mediates interactions with Ras and other small GTPases, and the SARAH domain mediates protein-protein interactions crucial in the pathways that induce cell cycle arrest and apoptosis. This model corresponds to the SARAH domain of RASSF1.

protein kinase C conserved region 1 (C1 domain) superfamily; The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains. It contains the motif HX12CX2CXnCX2CX4HX2CX7C, where C and H are cysteine and histidine, respectively; X represents other residues; and n is either 13 or 14. C1 has a globular fold with two separate Zn(2+)-binding sites. It was originally discovered as lipid-binding modules in protein kinase C (PKC) isoforms. C1 domains that bind and respond to phorbol esters (PE) and diacylglycerol (DAG) are referred to as typical, and those that do not respond to PE and DAG are deemed atypical. A C1 domain may also be referred to as PKC or non-PKC C1, based on the parent protein's activity. Most C1 domain-containing non-PKC proteins act as lipid kinases and scaffolds, except PKD which acts as a protein kinase. PKC C1 domains play roles in membrane translocation and activation of the enzyme.

protein kinase C conserved region 1 (C1 domain) found in the kinase suppressor of Ras (KSR) family; KSR is a scaffold protein that functions downstream of Ras and upstream of Raf in the Extracellular signal-Regulated Kinase (ERK) pathway that regulates many cellular processes including cycle regulation, proliferation, differentiation, survival, and apoptosis. KSR proteins regulate the assembly and activation of the Raf/MEK/ERK module upon Ras activation at the membrane by direct association of its components. They are widely regarded as pseudokinases, but there is some debate in this designation as a few groups have reported detecting kinase catalytic activity for KSRs, specifically KSR1. Vertebrates contain two KSR proteins, KSR1 and KSR2. KSR proteins contain a SAM-like domain, a zinc finger cysteine-rich domain (C1), and a pseudokinase domain. This model describes the C1 domain. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

protein kinase C conserved region 1 (C1 domain) found in tensin-2 like (TNS2-like) proteins; The TNS2-like group includes TNS2, and variants of TNS1 and TNS3. Tensin-2 (TNS2), also called C1 domain-containing phosphatase and tensin (C1-TEN), or tensin-like C1 domain-containing phosphatase (TENC1), is an essential component for the maintenance of glomerular basement membrane (GBM) structures. It regulates cell motility and proliferation. It may have phosphatase activity. TNS2 reduces AKT1 phosphorylation, lowers AKT1 kinase activity and interferes with AKT1 signaling. Tensin-1 (TNS1) plays a role in fibrillar adhesion formation. It may be involved in cell migration, cartilage development and in linking signal transduction pathways to the cytoskeleton. Tensin-3 (TNS3), also called tensin-like SH2 domain-containing protein 1 (TENS1), or tumor endothelial marker 6 (TEM6), may play a role in actin remodeling. It is involved in the dissociation of the integrin-tensin-actin complex. Typical TNS1 and TNS3 do not contain C1 domains, but some isoforms/variants do. Members of this family contain an N-terminal region with a zinc finger (C1 domain), a protein tyrosine phosphatase (PTP)-like domain and a protein kinase 2 (C2) domain, and a C-terminal region with SH2 and pTyr binding (PTB) domains. This model corresponds to C1 domain. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

Ras-associating (RA) domain found in Ras-association domain-containing protein 4 (RASSF4); RASSF4 is a member of a family of six related classical RASSF1-6 proteins and is broadly expressed in normal tissues. RASSF4 expression is reduced in tumor cell lines and primary tumors by promoter specific hypermethylation. RASSF4 contains the RA and SARAH domains. The RA domain of the classical RASSF protein family has the beta-grasp ubiquitin-like fold with low sequence similarity to ubiquitin. RA domains mediate interactions with Ras and other small GTPases, and SARAH domains mediate protein-protein interactions crucial in the pathways that induce cell cycle arrest and apoptosis. RASSF4 inhibits lung cancer cell proliferation and invasion.

C-terminal SARAH domain found in Ras-association domain proteins, RASSF2, RASSF4, and RASSF6; The RASSF subfamily of proteins shares a conserved RalGDS/AF6 Ras association (RA) domain which is located either at the C-terminus (RASSF1-6, the classical group) or at the N-terminus (RASSF7-10). The classical RASSF proteins seem to modulate some of the growth inhibitory responses mediated by Ras and may serve as tumor suppressor genes. They interact either directly or indirectly with activated Ras. Ras proteins are small GTPases that are involved in cellular signal transduction. RASSF1-6 contain a conserved C-terminal SARAH (Salvador-RassF-Hippo) motif adjacent to the RA domain that functions in scaffolding and regulatory interactions. The RA domain of the classical RASSF proteins has a beta-grasp ubiquitin-like fold with low sequence similarity to ubiquitin. This model corresponds to the SARAH domain of RASSF2, RASSF4, and RASSF6. It is a characteristic coiled-coil structure that is important in signal-transduction networks. The central function of the SARAH domain is the mediation of homo- and heterodimerization between SARAH domain-containing proteins.

protein kinase C conserved region 1 (C1 domain) found in the 190 kDa guanine nucleotide exchange factor (p190RhoGEF)-like family; The p190RhoGEF-like protein family includes p190RhoGEF, Rho guanine nucleotide exchange factor 2 (ARHGEF2), A-kinase anchor protein 13 (AKAP-13) and similar proteins. p190RhoGEF is a brain-enriched, RhoA-specific guanine nucleotide exchange factor that regulates signaling pathways downstream of integrins and growth factor receptors. It is involved in axonal branching, synapse formation and dendritic morphogenesis, as well as in focal adhesion formation, cell motility and B-lymphocytes activation. ARHGEF2 acts as a guanine nucleotide exchange factor (GEF) that activates Rho-GTPases by promoting the exchange of GDP for GTP. It is thought to play a role in actin cytoskeleton reorganization in different tissues since its activation induces formation of actin stress fibers. AKAP-13 is a scaffold protein that plays an important role in assembling signaling complexes downstream of several types of G protein-coupled receptors. It activates RhoA in response to signaling via G protein-coupled receptors via its function as Rho guanine nucleotide exchange factor. It may also activate other Rho family members. AKAP-13 plays a role in cell growth, cell development and actin fiber formation. Members of this family share a common domain architecture containing C1, RhoGEF or Dbl-homologous (DH), and Pleckstrin Homology (PH) domains. Some members may contain additional domains such as the DUF5401 domain. This model describes the C1 domain.

protein kinase C conserved region 1 (C1 domain) found in the RAS guanyl-releasing protein (RASGRP) family; The RASGRP family includes RASGRP1-4. They function as cation-, usually calcium-, and diacylglycerol (DAG)-regulated nucleotide exchange factor activating Ras through the exchange of bound GDP for GTP. RASGRP1, also called calcium and DAG-regulated guanine nucleotide exchange factor II (CalDAG-GEFII) or Ras guanyl-releasing protein, activates the Erk/MAP kinase cascade and regulates T-cell/B-cell development, homeostasis and differentiation by coupling T-lymphocyte/B-lymphocyte antigen receptors to Ras. RASGRP1 also regulates NK cell cytotoxicity and ITAM-dependent cytokine production by activation of Ras-mediated ERK and JNK pathways. RASGRP2, also called calcium and DAG-regulated guanine nucleotide exchange factor I (CalDAG-GEFI), Cdc25-like protein (CDC25L), or F25B3.3 kinase-like protein, specifically activates Rap and may also activate other GTPases such as RRAS, RRAS2, NRAS, KRAS but not HRAS. RASGRP2 is involved in aggregation of platelets and adhesion of T-lymphocytes and neutrophils probably through inside-out integrin activation, as well as in the muscarinic acetylcholine receptor M1/CHRM1 signaling pathway. RASGRP3, also called calcium and DAG-regulated guanine nucleotide exchange factor III (CalDAG-GEFIII), or guanine nucleotide exchange factor for Rap1, is a guanine nucleotide-exchange factor activating H-Ras, R-Ras and Ras-associated protein-1/2. It functions as an important mediator of signaling downstream from receptor coupled phosphoinositide turnover in B and T cells. RASGRP4 may function in mast cell differentiation.

Stac1 and Stac2 have been found to be expressed differently in mature dorsal root ganglia (DRG) neurons. Stac1 is mainly expressed in peptidergic neurons while Stac2 is found in a subset of nonpeptidergic and all trkB+ neurons. Stac proteins contain a cysteine-rich C1 domain and one or two SH3 domains at the C-terminus. This model corresponds to the C1 domain. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

first protein kinase C conserved region 1 (C1 domain) found in Caenorhabditis elegans serine/threonine-protein kinase DKF-1 and similar proteins; DKF-1 converts transient diacylglycerol (DAG) signals into prolonged physiological effects, independently of PKC. It plays a role in the regulation of growth and neuromuscular control of movement. It is involved in immune response to Staphylococcus aureus bacterium by activating transcription factor hlh-30 downstream of phospholipase plc-1. Members of this group contain two copies of the C1 domain. This model corresponds to the first one. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

protein kinase C conserved region 1 (C1 domain) found in alpha-chimaerin and similar proteins; Alpha-chimaerin, also called A-chimaerin, N-chimaerin (CHN), alpha-chimerin, N-chimerin (NC), or Rho GTPase-activating protein 2 (ARHGAP2), is a GTPase-activating protein (GAP) for p21-rac and a phorbol ester receptor. It is involved in the assembly of neuronal locomotor circuits as a direct effector of EPHA4 in axon guidance. Alpha-chimaerin contains a functional SH2 domain that can bind to phosphotyrosine motifs within receptors, a GAP domain with specificity in vitro for Rac1 and a diacylglycerol (DAG)-binding C1 domain which allows them to translocate to membranes in response to DAG signaling and anchors them in close proximity to activated Rac. This model corresponds to the C1 domain. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

first protein kinase C conserved region 1 (C1 domain) found in type I diacylglycerol kinases; Diacylglycerol (DAG) kinase (EC 2.7.1.107) is a lipid kinase that phosphorylates diacylglycerol to form phosphatidic acid. Type I DAG kinases (DGKs) contain EF-hand structures that bind Ca(2+) and recoverin homology domains, in addition to C1 and catalytic domains that are present in all DGKs. Type I DGKs, regulated by calcium binding, include three DGK isozymes (alpha, beta and gamma). DAG kinase alpha, also called 80 kDa DAG kinase, or diglyceride kinase alpha (DGK-alpha), is active upon cell stimulation, initiating the resynthesis of phosphatidylinositols and attenuating protein kinase C activity. DAG kinase beta, also called 90 kDa DAG kinase, or diglyceride kinase beta (DGK-beta), exhibits high phosphorylation activity for long-chain diacylglycerols. DAG kinase gamma, also called diglyceride kinase gamma (DGK-gamma), reverses the normal flow of glycerolipid biosynthesis by phosphorylating diacylglycerol back to phosphatidic acid. Members of this family contain two copies of the C1 domain. This model corresponds to the first one. DGK-alpha contains atypical C1 domains, while DGK-beta and DGK-gamma contain typical C1 domains that bind DAG and phorbol esters. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.

protein kinase C conserved region 1 (C1 domain) found in RAS guanyl-releasing protein 2 (RASGRP2) and similar proteins; RASGRP2, also called calcium and DAG-regulated guanine nucleotide exchange factor I (CalDAG-GEFI), Cdc25-like protein (CDC25L), or F25B3.3 kinase-like protein, functions as a calcium- and DAG-regulated nucleotide exchange factor specifically activating Rap through the exchange of bound GDP for GTP. It may also activate other GTPases such as RRAS, RRAS2, NRAS, KRAS but not HRAS. RASGRP2 is also involved in aggregation of platelets and adhesion of T-lymphocytes and neutrophils probably through inside-out integrin activation, as well as in the muscarinic acetylcholine receptor M1/CHRM1 signaling pathway. The C1 domain is a cysteine-rich zinc binding domain that does not bind DNA nor possess structural similarity to conventional zinc finger domains; it contains two separate Zn(2+)-binding sites.
