AP1S2(Adaptor Protein 1 Sigma 2 Subunit)是AP-1复合体的一个亚基,属于衔接蛋白(adaptor protein)家族的一员。AP-1复合体由四个亚基组成(γ、β1、μ1和σ1/σ2),主要参与高尔基体到内体或质膜的囊泡运输,调控蛋白质的分选和运输过程。AP1S2在神经系统中表达较高,尤其在突触形成和神经元发育中起关键作用。该基因位于X染色体(Xp22.2),突变可能导致X连锁智力障碍(如X-linked intellectual disability, XLID)和癫痫等神经系统疾病。AP1S2突变通常影响AP-1复合体的组装或功能,导致突触囊泡运输异常,进而干扰神经递质释放和突触可塑性。过表达AP1S2可能扰乱囊泡运输平衡,影响神经元信号传导;而表达降低则可能导致突触功能障碍,与认知缺陷相关。AP1S2属于σ亚基家族(包括AP1S1、AP1S2、AP1S3等),这些成员在结构上具有相似性,均包含一个σ亚基特有的结构域,负责与其他亚基或货物蛋白相互作用。AP1S2还与某些神经退行性疾病(如阿尔茨海默病)的病理过程相关,可能通过影响淀粉样前体蛋白(APP)的运输途径发挥作用。

Adaptor protein complex 1 is found at the cytoplasmic face of coated vesicles located at the Golgi complex, where it mediates both the recruitment of clathrin to the membrane and the recognition of sorting signals within the cytosolic tails of transmembrane receptors. This complex is a heterotetramer composed of two large, one medium, and one small adaptin subunit. The protein encoded by this gene serves as the small subunit of this complex and is a member of the adaptin protein family. Transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2013]

适配器蛋白复合物1在位于高尔基复合体,在那里它介导网格蛋白的至膜既招募和跨膜受体的胞质尾部内分选信号的识别涂覆囊泡的胞质面找到。这种复杂的是两个大,一个媒体,一个小adaptin亚基组成的异四聚体。由该基因编码的蛋白质可作为这种复杂的小亚基,并且是adaptin蛋白家族的一个成员。已发现该基因编码不同亚型抄本变形。 [由RefSeq的,2013年1月提供]
