Protein tyrosine phosphatase-like domains of phytases and similar domains; This subfamily contains the tandem protein tyrosine phosphatase (PTP)-like domains of protein tyrosine phosphatase-like phytases (PTPLPs) and similar domains including the PTP domain of Pseudomonas syringae tyrosine-protein phosphatase hopPtoD2. PTPLPs, also known as cysteine phytases, are one of four known classes of phytases, enzymes that degrade phytate (inositol hexakisphosphate [InsP(6)]) to less-phosphorylated myo-inositol derivatives. Phytate is the most abundant cellular inositol phosphate and plays important roles in a broad scope of cellular processes, including DNA repair, RNA processing and export, development, apoptosis, and pathogenicity. PTPLPs adopt a PTP fold, including the active-site signature sequence (CX5R(S/T)) and utilize a classical PTP reaction mechanism. However, these enzymes display no catalytic activity against classical PTP substrates due to several unique structural features that confer specificity for myo-inositol polyphosphates.

Inositol hexakisphosphate; Inositol hexakisphosphate, often called phytate, is found in abundance in seeds and acting as an inorganic phosphate reservoir. Phytases are phosphatases that hydrolyze phytate to less-phosphorylated myo-inositol derivatives and inorganic phosphate. The active-site sequence (HCXXGXGR) of the phytase identified from the gut micro-organizm Selenomonas ruminantium forms a loop (P loop) at the base of a substrate binding pocket that is characteriztic of protein tyrosine phosphatases (PTPs). The depth of this pocket is an important determinant of the substrate specificity of PTPs. In humans this enzyme is thought to aid bone mineralization and salvage the inositol moiety prior to apoptosis.

1.83e-08
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 23; Dual specificity phosphatase 23 (DUSP23), also known as VH1-like phosphatase Z (VHZ) or low molecular mass dual specificity phosphatase 3 (LDP-3), functions as a protein-serine/threonine phosphatase (EC 3.1.3.16) and a protein-tyrosine-phosphatase (EC 3.1.3.48). It deactivates its MAPK substrates by dephosphorylating the threonine and tyrosine residues in the conserved Thr-Xaa-Tyr motif residing in their activation sites. DUSP23 is an atypical DUSP; it contains the catalytic dual specificity phosphatase domain but lacks the N-terminal Cdc25/rhodanese-like domain that is present in typical DUSPs or MKPs. It is able to enhance activation of JNK and p38 MAPK, and has been shown to dephosphorylate p44-ERK1 (MAPK3) in vitro. It has been associated with cell growth and human primary cancers. It has also been identified as a cell-cell adhesion regulatory protein; it promotes the dephosphorylation of beta-catenin at Tyr 142 and enhances the interaction between alpha- and beta-catenin.

catalytic domain of tyrosine-protein phosphatase non-receptor type 20 and type 13; Tyrosine-protein phosphatase non-receptor type 20 (PTPN20) and type 13 (PTPN13, also known as PTPL1) belong to the family of classical tyrosine-specific protein tyrosine phosphatases (PTPs). PTPs (EC 3.1.3.48) catalyze the dephosphorylation of phosphotyrosine peptides. Human PTPN20 is a widely expressed phosphatase with a dynamic subcellular distribution that is targeted to sites of actin polymerization. Human PTPN13 is an important regulator of tumor aggressiveness.
