G蛋白偶联受体(GPCRs)是最大的细胞膜受体家族,具有七螺旋跨膜肽段结构。近年来,越来越多的研究认为这些受体以二聚体的形式参与调节生理活动,对信号识别及转导有重要作用。随着生物技术及分子生物学的发展,GPCRs二聚体研究已取得了很大的进展。该文就这些方面及同源、异源二聚体对受体结合及信号转导的重要作用作一简述。
G-protein coupled receptors (GPCRs) belong to the biggest subfamily of transmembran receptors. Recently, more and more research has been suggested that the dimerization of GPCRs may regulate the physiological and pharmacological activity. With the development of biochemistry technology and molecular biology, a great progress has been achieved in the field of the dimerization of GPCRs. This article will generally demonstrate that the vital roles of the homodimerization and heterdimerization.
