Caspase-9 (ICE-LAP6, Mch6) is an important member of the cysteine aspartic acid protease (caspase) family (1,2). Upon apoptotic stimulation, cytochrome c released from mitochondria associates with the 47 kDa procaspase-9/Apaf 1. Apaf-1 mediated activation of caspase-9 involves instrinsic proteolytic processing resulting in cleavage at Asp315 and producing a p35 subunit. Additional cleavage occurs at Asp330 producing a p37 subunit that can serve to amplify the apoptotic response (3-6). Cleaved caspase-9 further processes other caspase members, including caspase-3 and caspase-7, to initiate a caspase cascade, which leads to apoptosis (7-10).

Caspase-9 (ICE-LAP6, Mch6)是半胱氨酸天冬氨酸蛋白水解酶(caspase)家族的重要成员(1,2)。凋亡信号刺激后,细胞色素C从线粒体释放,这和47 kDa procaspase-9/Apaf 1有关。Apaf-1介导的caspase-9 活化,包括蛋白水解过程导致的caspase-9在Asp315处裂解并产生p35亚单位。另外一种裂解发生在Asp330处,产生p37亚单位,可以放大凋亡反应(3-6)。Cleaved caspase-9 进一步促进其他 caspase 家族成员的作用,包括 caspase-3 and caspase-7,并启动凋亡级联反应,最终导致凋亡。
