Protein Classification

protein-tyrosine phosphatase family protein( domain architecture ID 1000023)

cys-based protein-tyrosine phosphatase (PTP) family protein may be a PTP or a dual-specificity phosphatase (DUSP or DSP), and may catalyze the dephosphorylation of target phosphoproteins at tyrosine or tyrosine and serine/threonine residues, respectively

65-96 1.71e-13

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.

65-96 1.71e-13

dual specificity phosphatase domain of dual specificity protein phosphatase 19; Dual specificity protein phosphatase 19 (DUSP19), also called low molecular weight dual specificity phosphatase 3 (LMW-DSP3) or stress-activated protein kinase (SAPK) pathway-regulating phosphatase 1 (SKRP1), functions as a protein-serine/threonine phosphatase (EC 3.1.3.16) and a protein-tyrosine-phosphatase (EC 3.1.3.48). It 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. DUSP19 interacts with the MAPK kinase MKK7, a JNK activator, and inactivates the JNK MAPK pathway.

69-96 3.08e-04

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.
