中文名称

突触粘附样分子

通路描述

受体和离子通道招募到突触后膜是突触形成的最后一步。许多这些蛋白质直接或间接地与突触后密度 -95(PSD95)/ 大盘/ 紧密连接蛋白 -1(PDZ)蛋白相互作用,从而将它们与突触后支架联系起来,并提供保留蛋白质在突触处以及将其与已知与 PDZ 蛋白结合的信号分子保持邻近的机制(Wang 等,2006 年;Morimura 等,2006 年;Ko 等,2006 年;Nourry 等,2003 年;Kim & Sheng 2004 年;Montgomery 等,2004 年;Sheng 和 Kim 2011 年)。突触粘附样分子(SALM)家族属于富含亮氨酸重复(LRR)的粘附分子超家族,也称为 LRFN(富含亮氨酸重复和纤维连接蛋白 III 结构域含),是连接 NMDA 和 AMPA 受体的突触粘附分子。该家族包含 5 个已知的成员(SALM 1-5 或 LRFN1-5),它们在神经元的突起生长和分支、突触形成和成熟中起调节作用。SALM 蛋白分布在神经元的树突和轴突中(Ko 等,2006 年;Wang 等,2006 年;Sebold 等,2012 年)。该家族成员 SALM1-SALM5 具有单个跨膜(TM)结构域,并含有细胞外富含亮氨酸重复结构域、Ig C2 结构域、纤维连接蛋白 III 结构域和细胞内突触后密度 -95(PSD-95)/ 大盘/ 紧密连接蛋白 -1(PDZ)结合结构域,该结构域存在于所有成员中,除了 SALM4 和 SALM5(Ko 等,2006 年;Wang 等,2006 年;Morimura 等,2006 年)。
英文描述
Synaptic adhesion-like molecules Recruitment of receptors and ion channels to the postsynaptic membrane is the last step in synapse formation. Many of these proteins interact directly or indirectly with postsynaptic density-95 (PSD95)/Discs large/zona occludens-1 (PDZ) proteins, thus linking them to the postsynaptic scaffold and providing a mechanism for both retaining the protein at the synapse and keeping its proximity to signaling molecules known to associate with PDZ proteins (Wang et al. 2006, Morimura et al. 2006, Ko et al. 2006, Nourry et al. 2003, Kim & Sheng 2004, Montgomery et al. 2004, Sheng and Kim 2011). The synaptic adhesion-like molecules (SALM) family belongs to the superfamily of leucine-rich repeat (LRR)-containing adhesion molecules, alternatively referred to as LRFN (leucine-rich repeat and fibronectin III domain-containing) is synapse adhesion molecule linked to NMDA and AMPA receptors. It includes five known members (SALMs 1-5 or LRFN1-5), which have been implicated in the regulation of neurite outgrowth and branching, and synapse formation and maturation. SALM proteins are distributed to both dendrites and axons in neurons (Ko et al. 2006, Wang et al. 2006, Sebold et al. 2012). The family members, SALM1-SALM5, have a single transmembrane (TM) domain and contain extracellular leucine-rich repeats, an Ig C2 type domain, a fibronectin type III domain, and an intracellular postsynaptic density-95 (PSD-95)/Discs large/zona occludens-1 (PDZ) binding domain, which is present on all members except SALM4 and SALM5 (Ko et al. 2006, Wang et al.2006, Morimura et al. 2006).
