产品说明
MKPs是一类丝氨酸/苏氨酸和酪氨酸双重底物特异性的磷酸酶 ,对于丝裂素活化蛋白激酶活性的调节起着十分重要的作用,可使丝裂素活化蛋白激酶上的苏氨酸/酪氨酸去磷酸化失活。目前研究发现MKPs分别有MKP-1、MKP-2、MKP-3及MKP4-6。 MKPs受MAPK信号通路中多种成分的诱导 ,决定了它与MAPK之间作用的特异性。 通过去磷酸化作用调节MAPK信号途径的活性 ,确保了细胞内信号的精确传递 ,参与了多种主要的细胞功能的调节。
The expression of DUSP1 gene is induced in human skin fibroblasts by oxidative/heat stress and growth factors. It specifies a protein with structural features similar to members of the non-receptor-type protein-tyrosine phosphatase family, and which has significant amino-acid sequence similarity to a Tyr/Ser-protein phosphatase encoded by the late gene H1 of vaccinia virus. The bacterially expressed and purified DUSP1 protein has intrinsic phosphatase activity, and specifically inactivates mitogen-activated protein (MAP) kinase in vitro by the concomitant dephosphorylation of both its phosphothreonine and phosphotyrosine residues. Furthermore, it suppresses the activation of MAP kinase by oncogenic ras in extracts of Xenopus oocytes. Thus, DUSP1 may play an important role in the human cellular response to environmental stress as well as in the negative regulation of cellular proliferation. mol wt:40kDa Other Aliases: Mitogen activated protein kinase phosphatase 1; CL 100; CL100; Dual Specificity Phosphatase 1; Dual specificity protein phosphatase 1; Dual specificity protein phosphatase hVH1; DUSP 1; EC 3.1.3.16; EC 3.1.3.48; HVH 1; HVH1; MAP kinase phosphatase 1; MKP 1; MKP1; Protein tyrosine phosphatase CL100; PTPN 10; PTPN10; Serine/threonine specific protein phosphatase; VH 1; VH1; 3ch134; Mkp1; Ptpn16
