摘 要: | calpain是钙激活中性蛋白酶,属于半胱氨酸蛋白水解酶超家族成员。是由分子量为80KD的催化亚单位和分子量为30KD的调解亚单位组成的异二聚体。研究最多的是calpain1和2,它们又称μ-calpain和m-calpain。calpain被认为与细胞骨架重塑、信号转导途径、调控细胞周期、基因表达调控、某些凋亡途径以及长程增强效应等有关。calpain参与了细胞凋亡,而calpain抑制剂可以阻止细胞的凋亡。

Abstract: | Calpains are a family of calcium-dependent cytosolic cysteine proteinases.The ubiquitous μ-and m-calpains(calpains I and II),the best characterized calpains by far,have been fully analyzed at the protein/enzyme level.They are heterodimers composed of a large 80-kDa catalytic subunit and a common 30-kDa regulatory subunit.The calpains are also implicated in physiological and pathophysiological processes,such as cytoskeletal reorganization,signal transduction pathways,cell cycle regulation,some apoptosis pathways and long-term potentiation.The calpains may play a role in the apoptotic process,since calpain inhibitors can supress cell apoptosis. |
