KLHL5参与蛋白质泛素化修饰的生物学意义

扫码查看
泛素化是一种重要的蛋白修饰方式,通过将泛素与靶蛋白共价结合,调节靶蛋白的功能和稳定性,在分子和细胞水平上调节免疫系统.最近的研究发现,肌动蛋白结合蛋白KLHL5参与了泛素化修饰的过程.KLHL5通过连接E3泛素连接酶和泛素的协同作用,调节多种细胞生理过程,包括蛋白酶体降解、转录调节、蛋白-蛋白质相互作用、内吞作用、自噬、DNA修复和细胞周期调节等.它对免疫系统的调节以及相关疾病的发生发展具有重要影响.文章回顾总结了KLHL5参与的泛素化过程对蛋白的修饰作用.
Biological Significance of KLHL5 in Protein Ubiquitination Modification
Ubiquitin is an important protein modification method,which regulates the function and stability of target proteins by covalently binding ubiquitin to target proteins,and regulates the immune system at the molecular and cellular levels.Recent studies have found that the actin-binding protein KLHL5 is involved in the process of ubiquitination modification.KLHL5 regulates a variety of cellular physiological processes,including proteasome degradation,transcription regulation,protein-protein interactions,endocytosis,autophagy,DNA repair,and cell cycle regulation,through the synergistic action of E3 ubiquitin ligase and ubiquitin.It has an important impact on the regulation of the immune system,and the occurrence and development of related diseases.The effect of ubiquitination process involving KLHL5 on protein modification was reviewed.
