ITSN1(Intersectin 1)属于Intersectin基因家族,该家族包括ITSN1和ITSN2两个成员,主要参与细胞内吞作用、囊泡运输和信号转导等过程。ITSN1编码的蛋白是一种支架蛋白,含有多个功能域,如EH结构域、SH3结构域和coiled-coil结构域,这些结构域使其能够与多种蛋白相互作用,调控细胞内的信号通路和膜运输。ITSN1在中枢神经系统中高表达,对突触形成和神经递质释放具有重要作用,同时也参与细胞骨架重组和细胞迁移。ITSN1的突变或表达异常可能与神经系统疾病如阿尔茨海默病和精神分裂症有关,因为这些疾病涉及突触功能紊乱。如果ITSN1过表达,可能导致突触过度活跃或信号通路异常激活,进而影响神经元的正常功能;而降低表达则可能损害突触可塑性,导致认知功能障碍。此外,ITSN1还参与受体酪氨酸激酶(如EGFR)的内吞和降解,其表达异常可能影响细胞增殖和肿瘤发生。ITSN基因家族的共性在于它们都含有多个蛋白相互作用域,能够整合多种信号通路,尤其在调控内吞和细胞骨架动力学中发挥核心作用。研究ITSN1的功能有助于理解神经系统疾病和癌症的分子机制,并为相关治疗提供潜在靶点。
The protein encoded by this gene is a cytoplasmic membrane-associated protein that indirectly coordinates endocytic membrane traffic with the actin assembly machinery. In addition, the encoded protein may regulate the formation of clathrin-coated vesicles and could be involved in synaptic vesicle recycling. This protein has been shown to interact with dynamin, CDC42, SNAP23, SNAP25, SPIN90, EPS15, EPN1, EPN2, and STN2. Multiple transcript variants encoding different isoforms have been found for this gene, but the full-length nature of only two of them have been characterized so far. [provided by RefSeq, Jul 2008]
