细胞凋亡又称为程序性细胞死亡,是多细胞生物维持生长发育和组织形态所特有的,由多种基因参与表达、精密调控的细胞主动死亡过程。NIX是近年来发现的隶属于Bcl-2家族中的BH3-only促凋亡家族成员。虽然具有Bcl-2家族特征性的BH3域和羧基末端跨膜结构域(TM),也能与Bcl-2形成二 Apoptosis, also known as programmed cell death, is a multicellular organism that is unique to the growth, development, and organization of cells, and is actively regulated by a variety of genes involved in the regulation of cell death. NIX is a member of the BH3-only pro-apoptotic family belonging to the Bcl-2 family found in recent years. Although having the BH3 domain and carboxy terminal transmembrane domain (TM) characteristic of the Bcl-2 family, it is also capable of forming bis
