该基因编码的蛋白是双特异性蛋白磷酸酶亚家族的一员。这些磷酸酶通过磷酸丝氨酸/苏氨酸和磷酸酪氨酸残基的去磷酸化使其靶激酶失活它们负性调节丝裂原活化蛋白激酶超家族(MAPK/ERK,SAPK/JNK,p38)的成员,这些成员与细胞增殖和分化有关双特异性磷酸酶家族的不同成员对不同的MAP激酶、不同的组织分布和亚细胞定位以及细胞外刺激诱导其表达的不同方式具有不同的底物特异性该基因产物使erk1和erk2失活,主要在造血组织中表达,并定位于细胞核。[由RefSeq提供,2008年7月]
The protein encoded by this gene is a member of the dual specificity protein phosphatase subfamily. These phosphatases inactivate their target kinases by dephosphorylating both the phosphoserine/threonine and phosphotyrosine residues. They negatively regulate members of the mitogen-activated protein (MAP) kinase superfamily (MAPK/ERK, SAPK/JNK, p38), which are associated with cellular proliferation and differentiation. Different members of the family of dual specificity phosphatases show distinct substrate specificities for various MAP kinases, different tissue distribution and subcellular localization, and different modes of inducibility of their expression by extracellular stimuli. This gene product inactivates ERK1 and ERK2, is predominantly expressed in hematopoietic tissues, and is localized in the nucleus. [provided by RefSeq, Jul 2008]
