摘要
线粒体自噬是一种清除受损或多余线粒体的过程,在调节细胞内线粒体质量和维持线粒体能量代谢等方面发挥重要作用.TANK结合激酶1(TANK-binding kinase 1,TBK1)是一种多功能的丝氨酸/苏氨酸蛋白激酶,同时参与调控PTEN诱导假定激酶1(PTEN-induced putative kinase 1,PINK1)/Parkin依赖性和非依赖性线粒体自噬过程.近期研究表明,TBK1可磷酸化视神经蛋白(optineurin,OPTN)、p62/sequestosome-1、Ras相关GTP结合蛋白7(Ras-related GTP binding protein 7,Rab7)等自噬相关蛋白,并介导核点蛋白52(nuclear dot protein 52,NDP52)与UNC-51 样自噬激活激酶 1(UNC-51 like autophagy activating kinase 1,ULK1)复合物相结合,以及 TAX1 结合蛋白 1(TAX1-binding protein 1,TAX1BP1)与微管相关蛋白 1 轻链 3(microtubule-associated protein 1 light chain 3,LC3)相结合,从而增强PINK1/Parkin依赖性线粒体自噬.TBK1亦可作为AMP活化蛋白激酶(AMP-activated protein kinase,AMPK)/ULK1自噬通路的作用底物而被激活,再通过磷酸化动力相关蛋白1(dynamin-related protein 1,Drp1)、Rab7促进PINK1/Parkin非依赖性线粒体自噬.本文对TBK1在PINK1/Parkin依赖性和非依赖性线粒体自噬中的作用及机制进行了综述.
Abstract
Mitophagy is a process that selectively removes excess or damaged mitochondria and plays an important role in regulating intracellular mitochondrial mass and maintaining mitochondrial energy metabolism.TANK-binding kinase 1(TBK1)is a multifunc-tional serine/threonine protein kinase,which is involved in the regulation of PTEN-induced putative kinase 1(PINK1)/Parkin-depen-dent and-independent mitophagy.Recent studies have shown that TBK1 phosphorylates the autophagy related proteins,such as optineurin(OPTN),p62/sequestosome-1,Ras-related GTP binding protein 7(Rab7),and mediates the binding of nuclear dot protein 52(NDP52)to UNC-51 like autophagy activating kinase 1(ULK1)complex,as well as the binding of TAX1-binding protein 1(TAX1BP1)to microtubule-associated protein 1 light chain 3(LC3),thereby enhancing PINK 1/Parkin-dependent mitophagy.In addition,TBK1 is a direct substrate of AMP-activated protein kinase(AMPK)/ULK1 pathway,and its activation phosphorylates dynamin-related protein 1(Drp1)and Rab7 to promote PINK1/Parkin-independent mitophagy.This article reviews the role and mechanism of TBK1 in regulating PINK1/Parkin-dependent and-independent mitophagy.
