PTPN13(protein tyrosine phosphatase non-receptor type 13),癌症关联基因,基因ID:5783,该基因编码的蛋白是蛋白酪氨酸磷酸酶(ptp)家族的一员。ptps是调节细胞生长、分化、有丝分裂周期和癌基因转化等多种细胞过程的信号分子。ptp是一种大的细胞内蛋白。它的c-末端有一个催化ptp结构域和两个主要结构域:一个具有五个pdz结构域的区域和一个与质膜和细胞骨架元素结合的ferm结构域。ptp通过pdz结构域与磷酸脱磷、fas受体和ikappabalpha相互作用。这表明它在fas介导的细胞程序性死亡中起作用。ptp还与gtpase激活蛋白相互作用,可能作为rho信号通路的调节因子。已经报道了四种选择性剪接的转录变体,它们编码不同的蛋白质。[由RefSeq提供,2008年10月]The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP is a large intracellular protein. It has a catalytic PTP domain at its C-terminus and two major structural domains: a region with five PDZ domains and a FERM domain that binds to plasma membrane and cytoskeletal elements. This PTP was found to interact with, and dephosphorylate, Fas receptor and IkappaBalpha thro。
