该基因编码的蛋白是蛋白酪氨酸磷酸酶(PTP)家族的成员。众所周知,PTP是调节多种细胞过程的信号分子,包括细胞生长、分化、有丝分裂周期和致癌转化。这种PTP具有一个细胞外区、一个跨膜区和两个串联的细胞内催化域,因此代表一种受体型PTP。细胞外区包含一个MEPRIN-A5抗原PTP(MAM)结构域、免疫球蛋白样和纤维连接蛋白III型重复序列。该PTP的蛋白结构域和小鼠对应物的表达模式表明其在中枢神经系统的信号转导和细胞粘附中的作用。该基因的两个选择性剪接转录变体编码不同的蛋白质,已被报道。
The protein encoded by this gene is a member of the protein tyrosine phosphatase (PTP) family. PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This PTP possesses an extracellular region, a single transmembrane region, and two tandem intracellular catalytic domains, and thus represents a receptor-type PTP. The extracellular region contains a meprin-A5 antigen-PTP (MAM) domain, Ig-like and fibronectin type III-like repeats. The protein domain structure and the expression pattern of the mouse counterpart of this PTP suggest its roles in both signal transduction and cellular adhesion in the central nervous system. Two alternatively spliced transcript variants of this gene, which encode distinct proteins, have been reported.
