生化机理
Semaphorin-4A又称Semaphorin-B、SEMA4A、Sema B和SEMAB,是一种单通道I型膜蛋白,属于semaphorin家族。它通过提供局部信号来指定生长轴突无法进入的区域,从而抑制轴突的延伸。Semaphorin-4A / SEMA4A 含有一个 Ig 样 C2- 型(免疫球蛋白样)结构域、一个 PSI 结构域和一个 Sema 结构域。SEMA4A 缺陷是导致视网膜感光细胞变性的 35 型色素性视网膜炎(RP35)的病因。患者通常会出现夜盲症和中周视野缺失。随着病情的发展,他们会丧失远周视野,最终也会丧失中心视力。SEMA4A 缺陷也是导致 1 型视锥-杆状营养不良症(CORD1)的病因,这是一种遗传性视网膜营养不良症,属于色素性视网膜病变。CORD的特征是眼底检查可见视网膜色素沉积,主要发生在黄斑区,最初是视锥光感受器缺失,随后是视杆细胞变性。半影蛋白是一种分泌型、跨膜和 GPI 连接蛋白,由富含半胱氨酸的半影蛋白结构域定义,在多种组织中发挥重要作用。人类有两种半角蛋白,果蝇有五种,DNA 病毒中有两种。线虫和甲壳类动物体内有半隐形蛋白,但非动物体内没有。根据系统发育树分析和附加蛋白基序的存在,它们被分为八类。半隐形蛋白与多种发育过程有关,如神经系统发育过程中的轴突导向和细胞迁移调控。
