摘要 神经元间的信息传递依赖于神经递质的释放,这一过程离不开正常有效的囊泡循环机制,突触囊泡循环是调控突触囊泡水平和维持神经递质释放的基础。囊泡回收则是循环过程中保证囊泡从突触前膜回收至胞内,参与新一轮囊泡形成和再生的重要保障。网格蛋白介导的内吞是突触囊泡回收的主要途径,衔接蛋白AP-2(adaptin-2)是参与这一内吞过程不同时期的关键蛋白,其通过绑定不同蛋白分子分别从结构和动力的层面参与了囊泡回收过程,AP-2对网格蛋白介导的突触囊泡胞吞过程具有重要意义。本文结合国内外最新研究报道,简要综述了AP-2的结构特点、分子基础、AP-2蛋白调控网格蛋白介导突触囊泡的胞吞及其与听力的关系。 Neural transmission is dependent on the release of neurotransmitter. Synaptic vesicle recycling is the basis of neurotransmitter release. Clathrin-mediated endocytosis plays a key role in the synaptic vesicle reformation. AP - 2 is a key protein in different periods of endocytosis, which can bind other protein molecules to regulate the vesicle recycling from the aspects of structure and dynamics. This review summarizes the molecular structure and characteristic of AP-2 and discusses the relationship between clathrin-mediated endocytosis and hearing.
