protein tyrosine phosphatase type IVA 3; Protein tyrosine phosphatase type IVA 3 (PTP-IVa3), also known as protein-tyrosine phosphatase of regenerating liver 3 (PRL-3), stimulates progression from G1 into S phase during mitosis and enhances cell proliferation, cell motility and invasive activity, and promotes cancer metastasis. It exerts its oncogenic functions through activation of PI3K/Akt, which is a key regulator of the rapamycin-sensitive mTOR complex 1. PRL-3 is a member of the PTP-IVa/PRL family of small, prenylated phosphatases that are the most oncogenic of all PTPs. PRLs associate with magnesium transporters of the cyclin M (CNNM) family, which results in increased intracellular magnesium levels that promote oncogenic transformation.

C-terminal dual-specificity phosphatase domain of CDC14 family proteins; The cell division control protein 14 (CDC14) family is highly conserved in all eukaryotes, although the roles of its members seem to have diverged during evolution. Yeast Cdc14, the best characterized member of this family, is a dual-specificity phosphatase that plays key roles in cell cycle control. It preferentially dephosphorylates cyclin-dependent kinase (CDK) targets, which makes it the main antagonist of CDK in the cell. Cdc14 functions at the end of mitosis and it triggers the events that completely eliminates the activity of CDK and other mitotic kinases. It is also involved in coordinating the nuclear division cycle with cytokinesis through the cytokinesis checkpoint, and in chromosome segregation. Cdc14 phosphatases also function in DNA replication, DNA damage checkpoint, and DNA repair. Vertebrates may contain more than one Cdc14 homolog; humans have three (CDC14A, CDC14B, and CDC14C). CDC14 family proteins contain a highly conserved N-terminal pseudophosphatase domain that contributes to substrate specificity and a C-terminal catalytic dual-specificity phosphatase domain with the PTP signature motif.

cys-based protein tyrosine phosphatase and dual-specificity phosphatase superfamily; This superfamily is composed of cys-based phosphatases, which includes classical protein tyrosine phosphatases (PTPs) as well as dual-specificity phosphatases (DUSPs or DSPs). They are characterized by a CxxxxxR conserved catalytic loop (where C is the catalytic cysteine, x is any amino acid, and R is an arginine). PTPs are part of the tyrosine phosphorylation/dephosphorylation regulatory mechanism, and are important in the response of the cells to physiologic and pathologic changes in their environment. DUSPs show more substrate diversity (including RNA and lipids) and include pTyr, pSer, and pThr phosphatases.

dual-specificity phosphatase domain; The dual-specificity phosphatase domain is found in typical and atypical dual-specificity phosphatases (DUSPs), which function as protein-serine/threonine phosphatases (EC 3.1.3.16) and protein-tyrosine-phosphatases (EC 3.1.3.48). Typical DUSPs, also called mitogen-activated protein kinase (MAPK) phosphatases (MKPs), deactivate MAPKs by dephosphorylating the threonine and tyrosine residues in the conserved Thr-Xaa-Tyr motif residing in their activation sites. All MKPs contain an N-terminal Cdc25/rhodanese-like domain, which is responsible for MAPK-binding, and a C-terminal catalytic dual specificity phosphatase domain. Atypical DUSPs contain the catalytic dual specificity phosphatase domain but lack the N-terminal Cdc25/rhodanese-like domain that is present in typical DUSPs or MKPs. Also included in this family are dual specificity phosphatase-like domains of catalytically inactive members such as serine/threonine/tyrosine-interacting protein (STYX) and serine/threonine/tyrosine interacting like 1 (STYXL1), as well as active phosphatases with substrates that are not phosphoproteins such as PTP localized to the mitochondrion 1 (PTPMT1), which is a lipid phosphatase, and laforin, which is a glycogen phosphatase.

protein-tyrosine phosphatase mitochondrial 1; Protein-tyrosine phosphatase mitochondrial 1 or PTP localized to the mitochondrion 1 (PTPMT1), also called phosphoinositide lipid phosphatase (PLIP), phosphatidylglycerophosphatase and protein-tyrosine phosphatase 1, or PTEN-like phosphatase, is a lipid phosphatase or phosphatidylglycerophosphatase (EC 3.1.3.27) which dephosphorylates phosphatidylglycerophosphate (PGP) to phosphatidylglycerol (PG). It is targeted to the mitochondrion by an N-terminal signal sequence and is found anchored to the matrix face of the inner membrane. It is essential for the biosynthesis of cardiolipin, a mitochondrial-specific phospholipid regulating the membrane integrity and activities of the organelle. PTPMT1 also plays a crucial role in hematopoietic stem cell (HSC) function, and has been shown to display activity toward phosphoprotein substrates.

catalytic domain of protein tyrosine phosphatases; Protein tyrosine phosphatases (PTP, EC 3.1.3.48) catalyze the dephosphorylation of phosphotyrosine peptides; they regulate phosphotyrosine levels in signal transduction pathways. The depth of the active site cleft renders the enzyme specific for phosphorylated Tyr (pTyr) residues, instead of pSer or pThr. This family has a distinctive active site signature motif, HCSAGxGRxG, and are characterized as either transmembrane, receptor-like or non-transmembrane (soluble) PTPs. Receptor-like PTP domains tend to occur in two copies in the cytoplasmic region of the transmembrane proteins, only one copy may be active.

protein tyrosine phosphatase-like domain of phosphatase and tensin homolog and similar proteins; Phosphatase and tensin homolog (PTEN) is a tumor suppressor that acts as a dual-specificity protein phosphatase and as a lipid phosphatase. It dephosphorylates phosphoinositide trisphosphate. In addition to PTEN, this family includes tensins, voltage-sensitive phosphatases (VSPs), and auxilins. They all contain a protein tyrosine phosphatase-like domain although not all are active phosphatases. Tensins are intracellular proteins that act as links between the extracellular matrix and the cytoskeleton, and thereby mediate signaling for cell shape and motility, and they may or may not have phosphatase activity. VSPs are phosphoinositide phosphatases with substrates that include phosphatidylinositol-4,5-diphosphate and phosphatidylinositol-3,4,5-trisphosphate. Auxilins are J domain-containing proteins that facilitate Hsc70-mediated dissociation of clathrin from clathrin-coated vesicles, and they do not exhibit phosphatase activity.

dual specificity phosphatase domain of laforin and similar domains; This family is composed of glucan phosphatases including vertebrate dual specificity protein phosphatase laforin, also called lafora PTPase (LAFPTPase), and plant starch excess4 (SEX4). Laforin is a glycogen phosphatase; its gene is mutated in Lafora progressive myoclonus epilepsy or Lafora disease (LD), a fatal autosomal recessive neurodegenerative disorder characterized by the presence of progressive neurological deterioration, myoclonus, and epilepsy. One characteristic of LD is the accumulation of insoluble glucans. Laforin prevents LD by at least two mechanisms: by preventing hyperphosphorylation of glycogen by dephosphorylating it, allowing proper glycogen formation, and by promoting the ubiquitination of proteins involved in glycogen metabolism via its interaction with malin. Laforin contains an N-terminal CBM20 (carbohydrate-binding module, family 20) domain and a C-terminal catalytic dual specificity phosphatase (DSP) domain. Plant SEX4 regulate starch metabolism by selectively dephosphorylating glucose moieties within starch glucan chains. It contains an N-terminal catalytic DSP domain and a C-terminal Early (E) set domain.

PTP-like domain of the LAR family receptor-type tyrosine-protein phosphatases, repeat 2; The LAR (leukocyte common antigen-related) family of receptor-type tyrosine-protein phosphatases (RPTPs) include three vertebrate members: LAR (or PTPRF), R-PTP-delta (or PTPRD), and R-PTP-sigma (or PTPRS). They belong to the larger family of classical tyrosine-specific protein tyrosine phosphatases (PTPs). PTPs (EC 3.1.3.48) catalyze the dephosphorylation of phosphotyrosine peptides. LAR-RPTPs are synaptic adhesion molecules; they bind to distinct synaptic membrane proteins and are physiologically responsible for mediating presynaptic development by shaping various synaptic adhesion pathways. They play roles in various aspects of neuronal development, including axon guidance, neurite extension, and synapse formation and function. LAR-RPTPs contain an extracellular region with three immunoglobulin-like (Ig) domains and four to eight fibronectin type III (FN3) repeats (determined by alternative splicing), a single transmembrane domain, followed by an intracellular region with a membrane-proximal catalytic PTP domain (repeat 1, also called D1) and a membrane-distal non-catalytic PTP-like domain (repeat 2, also called D2). This model represents the non-catalytic PTP-like domain (repeat 2).

dual specificity phosphatase domain of class II mitogen-activated protein kinase phosphatase; Mitogen-activated protein kinase (MAPK) phosphatases (MKPs) are eukaryotic dual-specificity phosphatases (DUSPs) that act on MAPKs and function as a protein-serine/threonine phosphatase (EC 3.1.3.16) and a protein-tyrosine-phosphatase (EC 3.1.3.48). They deactivate MAPKs by dephosphorylating the threonine and tyrosine residues in the conserved Thr-Xaa-Tyr motif residing in their activation sites. Based on sequence homology, subcellular localization and substrate specificity, 10 MKPs can be subdivided into three subfamilies (class I-III). Class II MKPs consist of DUSP6/MKP-3, DUSP7/MKP-X and DUSP9/MKP-4, and are ERK-selective cytoplasmic MKPs. All MKPs contain an N-terminal Cdc25/rhodanese-like domain, which is responsible for MAPK-binding, and a C-terminal catalytic dual specificity phosphatase domain.

PTP-like domain of receptor-type tyrosine-protein phosphatase F, repeat 2; Receptor-type tyrosine-protein phosphatase F (PTPRF), also known as leukocyte common antigen related (LAR), is the prototypical member of the LAR family of receptor-type tyrosine-protein phosphatases (RPTPs), which belong to the larger family of classical tyrosine-specific protein tyrosine phosphatases (PTPs). PTPs (EC 3.1.3.48) catalyze the dephosphorylation of phosphotyrosine peptides. PTPRF/LAR plays a role for LAR in cadherin complexes where it associates with and dephosphorylates beta-catenin, a pathway which may be critical for cadherin complex stability and cell-cell association. It also regulates focal adhesions through cyclin-dependent kinase-1 and is involved in axon guidance in the developing nervous system. It also functions in regulating insulin signaling. PTPRF contains an extracellular region with three immunoglobulin-like (Ig) domains and four to eight fibronectin type III (FN3) repeats (determined by alternative splicing), a single transmembrane domain, followed by an intracellular region with a membrane-proximal catalytic PTP domain (repeat 1, also called D1) and a membrane-distal non-catalytic PTP-like domain (repeat 2, also called D2).

dual specificity phosphatase and pro isomerase domain containing 1; Dual specificity phosphatase and pro isomerase domain containing 1 (DUPD1) was initially named as such because computational prediction appeared to encode a protein of 446 amino acids in length that included two catalytic domains: a proline isomerase and a dual specificity phosphatase (DUSP). However, it was subsequently shown that the true open reading frame only encompassed the DUSP domain and the gene product was therefore renamed DUSP27. This is distinct from inactive DUSP27. DUSPs function as protein-serine/threonine phosphatases (EC 3.1.3.16) and protein-tyrosine-phosphatases (EC 3.1.3.48). DUPD1/DUSP27 has been shown to have catalytic activity with preference for phosphotyrosine over phosphothreonine and phosphoserine residues. It associates with the short form of the prolactin (PRL) receptor and plays a role in PRL-mediated MAPK inhibition in ovarian cells.

protein tyrosine phosphatase-like domain of tensin-3; Tensin-3 (TNS3) is also called tensin-like SH2 domain-containing protein 1 (TENS1) or tumor endothelial marker (TEM6). It is part of the tensin family of intracellular proteins (tensin-1, -2, -3 and -4), which act as links between the extracellular matrix and the cytoskeleton, and thereby mediate signaling for cell shape and motility. Tensin-3 contributes to cell migration, anchorage-independent growth, tumorigenesis, and metastasis of cancer cells. It cooperates with Dock5, an exchange factor for the small GTPase Rac, for osteoclast activity to ensure the correct organization of podosomes. Tensin-3 contains an N-terminal region with a protein tyrosine phosphatase (PTP)-like domain followed by a protein kinase 2 (C2) domain, and a C-terminal region with SH2 and pTyr binding (PTB) domains.

dual specificity phosphatase domain of dual specificity protein phosphatase 22, 15, and similar proteins; Dual specificity protein phosphatase 22 (DUSP22, also known as VHX) and 15 (DUSP15, also known as VHY) function as protein-serine/threonine phosphatases (EC 3.1.3.16) and protein-tyrosine-phosphatases (EC 3.1.3.48). They are atypical DUSPs; they contain the catalytic dual specificity phosphatase domain but lack the N-terminal Cdc25/rhodanese-like domain that is present in typical DUSPs or MKPs. The both contain N-terminal myristoylation recognition sequences and myristoylation regulates their subcellular location. DUSP22 negatively regulates the estrogen receptor-alpha-mediated signaling pathway and the IL6-leukemia inhibitory factor (LIF)-STAT3-mediated signaling pathway. DUSP15 has been identified as a regulator of oligodendrocyte differentiation. DUSP22 is a single domain protein containing only the catalytic dual specificity phosphatase domain while DUSP15 contains a short C-terminal tail.
