中文名称

受体酪氨酸蛋白磷酸酶

通路描述

与神经节苷脂类似,受体酪氨酸蛋白磷酸酶(RPTPs)与多个突触后结合伙伴形成跨突触粘附复合物,以调节突触组织。IIa型RPTPs包括三种成员:受体酪氨酸蛋白磷酸酶F(PTPRF,有时称为白细胞共同抗原相关蛋白LAR)、受体酪氨酸蛋白磷酸酶σ(PTPRS)和受体酪氨酸蛋白磷酸酶δ(PTPRD)。这些蛋白质包含典型的细胞粘附免疫球蛋白样(Ig)和纤维连接蛋白III(FNIII)结构域,表明RPTPs在细胞 - 细胞和细胞 - 基质相互作用中起作用。迄今为止,已报道了六种不同类型的IIa型RPTPs突触后组织者:白细胞介素 - 1受体辅助蛋白(IL1RAP,IL-1RAcP)(Yoshida等,2012)、IL-1RAcP-like - 1(IL1RAPL1)(Yoshida等,2011)、神经生长因子受体酪氨酸激酶3(NTRK3,TrkC)(Takahashi等,2011)、富含亮氨酸重复结构域蛋白4B(LRRC4B,Netrin - G配体 - 3,NGL - 3)(Woo等,2009,Kwon等,2010)、Slit - 和Trk样(Slitrk)家族蛋白(Takahashi等,2012,Yim等,2013,Yamagata等,2015)和脂蛋白(Serra - Pagés等,1998,Dunah等,2005)。
英文描述
Receptor-type tyrosine-protein phosphatases Like neurexins, Receptor-like protein tyrosine phosphatases (RPTPs) make trans-synaptic adhesion complexes with multiple postsynaptic binding partners to regulate synapse organization. The type IIa RPTPs include three members, Receptor-type tyrosine-protein phosphatase F (PTPRF) sometimes referred to as leukocyte common antigen-related (LAR), Receptor-type tyrosine-protein phosphatase sigma (PTPRS) and Receptor-type tyrosine-protein phosphatase delta (PTPRD). These proteins contain typical cell adhesion immunoglobulin-like (Ig) and fibronectin III (FNIII) domains, suggesting the involvement of RPTPs in cell-cell and cell-matrix interactions. To date, six different types of postsynaptic organizers for type-IIa RPTPs have been reported: interleukin-1 receptor accessory protein (IL1RAP, IL-1RAcP) (Yoshida et al. 2012), IL-1RAcP-like-1 (IL1RAPL1) (Yoshida et al. 2011), Neurotrophin receptor tyrosine kinase 3 (NTRK3, TrkC) (Takahashi et al. 2011), Leucine-rich repeat-containing protein 4B (LRRC4B, Netrin-G ligand-3, NGL-3) (Woo et al. 2009, Kwon et al. 2010), the Slit- and Trk-like (Slitrk) family proteins (Takahashi et al. 2012, Yim et al. 2013, Yamagata et al. 2015) and the liprins (Serra-Pagès et al. 1998, Dunah et al. 2005).
