protein tyrosine phosphatase type IVA family; Protein tyrosine phosphatases type IVA (PTP-IVa), also known as protein-tyrosine phosphatases of regenerating liver (PRLs) constitute a family of small, prenylated phosphatases that are the most oncogenic of all PTPs. They stimulate progression from G1 into S phase during mitosis and enhances cell proliferation, cell motility and invasive activity, and promotes cancer metastasis. They associate with magnesium transporters of the cyclin M (CNNM) family, which results in increased intracellular magnesium levels that promote oncogenic transformation. Vertebrates contain three members: PRL-1, PRL-2, and PRL-3.

protein tyrosine phosphatase type IVA 1; Protein tyrosine phosphatase type IVA 1 (PTP-IVa1), also known as protein-tyrosine phosphatase of regenerating liver 1 (PRL-1), stimulates progression from G1 into S phase during mitosis and enhances cell proliferation, cell motility and invasive activity, and promotes cancer metastasis. It may play a role in the development and maintenance of differentiating epithelial tissues. PRL-1 promotes cell growth and migration by activating both the ERK1/2 and RhoA pathways. It 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.

cyclin-dependent kinase inhibitor 3 and similar proteins; This family is composed of eukaryotic cyclin-dependent kinase inhibitor 3 (CDKN3) and related archaeal and bacterial proteins. CDKN3 is also known as kinase-associated phosphatase (KAP), CDK2-associated dual-specificity phosphatase, cyclin-dependent kinase interactor 1 (CDI1), or cyclin-dependent kinase-interacting protein 2 (CIP2). It has been characterized as dual-specificity phosphatase, which function as a protein-serine/threonine phosphatase (EC 3.1.3.16) and protein-tyrosine-phosphatase (EC 3.1.3.48). It dephosphorylates CDK2 at a threonine residue in a cyclin-dependent manner, resulting in the inhibition of G1/S cell cycle progression. It also interacts with CDK1 and controls progression through mitosis by dephosphorylating CDC2. CDKN3 may also function as a tumor suppressor; its loss of function was found in a variety of cancers including glioblastoma and hepatocellular carcinoma. However, it has also been found over-expressed in many cancers such as breast, cervical, lung and prostate cancers, and may also have an oncogenic function.

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.

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). This model represents the non-catalytic PTP-like domain (repeat 2). Although described as non-catalytic, this domain contains the catalytic cysteine and the active site signature motif, HCSAGxGRxG.

PTP-like domain of receptor-type tyrosine-protein phosphatase S, repeat 2; Receptor-type tyrosine-protein phosphatase S (PTPRS), also known as receptor-type tyrosine-protein phosphatase sigma (R-PTP-sigma), belongs to the LAR (leukocyte common antigen-related) 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. PTPRS is a receptor for glycosaminoglycans, including heparan sulfate proteoglycan and neural chondroitin sulfate proteoglycans (CSPGs), which present a barrier to axon regeneration. It also plays a role in stimulating neurite outgrowth in response to the heparan sulfate proteoglycan GPC2. PTPRS 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).

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).

protein tyrosine phosphatase-like catalytic domain of phosphatase and tensin homolog; Phosphatase and tensin homolog (PTEN), also phosphatidylinositol 3,4,5-trisphosphate 3-phosphatase and dual-specificity protein phosphatase PTEN or mutated in multiple advanced cancers 1 (MMAC1), is a tumor suppressor that acts as a dual-specificity protein phosphatase and as a lipid phosphatase. It is a critical endogenous inhibitor of phosphoinositide signaling. It dephosphorylates phosphoinositide trisphosphate, and therefore, has the function of negatively regulating Akt. The PTEN/PI3K/AKT pathway regulates the signaling of multiple biological processes such as apoptosis, metabolism, cell proliferation, and cell growth. PTEN contains an N-terminal PIP-binding domain, a protein tyrosine phosphatase (PTP)-like catalytic domain, a regulatory C2 domain responsible for its cellular location, a C-tail containing phosphorylation sites, and a C-terminal PDZ domain.

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.

dual specificity phosphatase-like domain of serine/threonine/tyrosine-interacting protein; Serine/threonine/tyrosine-interacting protein (STYX), also called protein tyrosine phosphatase-like protein, is a catalytically inactive member of the protein tyrosine phosphatase family that plays an integral role in regulating pathways by competing with active phosphatases for binding to MAPKs. It acts as a nuclear anchor for MAPKs, affecting their nucleocytoplasmic shuttling.

dual specificity phosphatase domain of class III 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 III MKPs consist of DUSP8, DUSP10/MKP-5 and DUSP16/MKP-7, and are JNK/p38-selective phosphatases, which are found in both the cell nucleus and cytoplasm. 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.
