摘要膜相关性鸟苷酸激酶(membrane associated guanylate kinase,MAGUK)是一类突触后致密蛋白(postsynaptic density,PSD),定位于突触后膜的突触后致密区,包括PSD-95、SAP-102、PSD-93和SAP-97.MAGUK家族成员含有多个蛋白结合位点,这些特殊的结合位点负责介导多种信号的转导.MAGUK参与中枢神经系统疾病发生和发展机制,已成为神经科学研究的热点.文章简要综述了MAGUK在缺血性脑损伤中的作用.

abstractsMembrane-associated guanylate kinases (MAGUKs) is a class of postsynaptic density proteins (PSDs) in the postsynaptic dense of the postsynaptic membrane,including PSD-95,SAP-102,PSD-93,and SAP-97.MAGUK family members contain several protein binding sites,and these special binding sites are responsible for mediating a variety of signal transduction.MAGUKs participate in the occurrence and development mechanisms in central nervous system diseases,and has become a topic of general interest of neuroscience.This article briefly reviews the roles of MAGUKs in ischemic brain injury.
