电压依赖性阴离子通道的研究进展

摘要

电压依赖性阴离子通道（ VDAC）位于线粒体外膜，形成了线粒体和代谢产物之间的分界，作为“守门员”控制着代谢产物的进出以及线粒体与其他细胞器的对话，同时，VDAC 也是线粒体介导凋亡的关键成员。除了调节线粒体的代谢和产能功能，VDAC 通过与不同配体和蛋白相互作用，作为细胞生存和死亡信号的汇聚点，这些功能可能使VDAC成为合理的新治疗发展的靶点。现就哺乳动物VDAC蛋白（尤其是VDAC1）的结构、功能、与相关蛋白的关系以及 VDAC 参与的疾病作一综述。%Found at the outer mitochondrial membrane , the voltage-dependent anion channel ( VDAC ) forms the main interface between the mitochondria and cellular metabolisms,thus functions as a gatekeeper, controlling cross-talk between mitochondria and the rest of the cell.Meanwhile,VDAC has also been recog-nized as a key protein in mitochondria-mediated apoptosis.In addition to regulating the metabolic and ener-getic functions of mitochondria,VDAC appears to be a convergence point for cell survival and cell death sig-nals via its association with various ligands and proteins ,making it to be a rational target for new therapeu-tics.Here is to make a review of mammalian VDAC ,especially VDAC1,addressing its structure,functions, the relationship between associated proteins and its involvement in several diseases .
