半胱天冬酶(半胱氨酸依赖性乙酰基特异性蛋白酶)属于半胱氨酸蛋白酶家族,其介导生物现象(如细胞死亡和炎症)不可或缺的蛋白水解事件。第一个半胱天冬酶被鉴定为线虫中凋亡细胞死亡的刽子手。此外,在从海绵到脊椎动物的各种动物中已经鉴定了大量的半胱天冬酶。半胱天冬酶被认为在细胞凋亡中起着关键作用,作为一种进化上保守的功能;然而,可以识别的半胱天冬酶的数量对于每个物种是不同的。这表明,物种特异性功能或多样化的生理作用已通过caspase进化培养。此外,最近的研究表明,半胱天冬酶也参与哺乳动物的炎症和细胞分化。本文综述了脊椎动物半胱天冬酶在其普遍和不同的功能,并提供了深入了解这些分子在动物中的生理作用。
Caspases (cysteine-dependent aspartyl-specific protease) belong to a family of cysteine proteases that mediate proteolytic events indispensable for biological phenomena such as cell death and inflammation. The first caspase was identified as an executioner of apoptotic cell death in the worm Caenorhabditis elegans. Additionally, a large number of caspases have been identified in various animals from sponges to vertebrates. Caspases are thought to play a pivotal role in apoptosis as an evolutionarily conserved function; however, the number of caspases that can be identified is distinct for each species. This indicates that species-specific functions or diversification of physiological roles has been cultivated through caspase evolution. Furthermore, recent studies suggest that caspases are also involved in inflammation and cellular differentiation in mammals. This review highlights vertebrate caspases in their universal and divergent functions and provides insight into the physiological roles of these molecules in animals.
