SYT1(突触结合蛋白1,Synaptotagmin 1)是一种钙离子敏感的突触小泡蛋白,属于突触结合蛋白(Synaptotagmin)基因家族,该家族共有17个成员(SYT1-17),主要参与调控神经递质释放和膜融合过程。SYT1作为突触前膜的关键钙传感器,通过其C2结构域(钙结合域)感知钙离子浓度变化,触发突触小泡与细胞膜融合,从而介导快速神经递质释放(如乙酰胆碱或谷氨酸),影响神经元间的信号传递。其表达主要集中在中枢和外周神经系统的突触前终端。SYT1功能缺失突变会导致严重的神经系统异常,如运动障碍、癫痫和智力残疾,这与突触传递效率下降直接相关。某些自闭症谱系障碍(ASD)患者中也发现SYT1错义突变,导致钙敏感性异常。过表达SYT1可能增强突触传递,但可能引发神经元过度兴奋或突触可塑性紊乱;而表达降低则导致神经递质释放障碍,与神经退行性疾病(如阿尔茨海默病)的突触功能障碍有关。SYT家族共性包括:均含有跨膜区和C2结构域,但不同成员具有组织特异性(如SYT1主要在神经元,SYT7则广泛表达)和钙敏感性差异。SYT1还与精神分裂症和帕金森病相关,其异常表达可能通过影响多巴胺能或谷氨酸能突触功能参与病理过程。

The synaptotagmins are integral membrane proteins of synaptic vesicles thought to serve as Ca(2+) sensors in the process of vesicular trafficking and exocytosis. Calcium binding to synaptotagmin-1 participates in triggering neurotransmitter release at the synapse (Fernandez-Chacon et al., 2001 [PubMed 11242035]).[supplied by OMIM, Jul 2010]

的synaptotagmins被认为是作为钙离子在囊泡运输和胞吐的过程传感器突触小泡的膜蛋白。在突触触发神经递质释放的钙结合到突触-1参与(费尔南德斯 - 查孔。等,2001年[搜索PubMed 11242035])。[由OMIM,2010年7月供给]
