Plays a role in the mitochondrial apoptotic process. Upon arrival of cell death signals, promotes mitochondrial outer membrane (MOM) permeabilization by oligomerizing to form pores within the MOM. This releases apoptogenic factors into the cytosol, including cytochrome c, promoting the activation of caspase 9 which in turn processes and activates the effector caspases.
基因名
BAK1
蛋白名
Bcl-2 homologous antagonist/killer
亚基
Belongs to the Bcl-2 family.
亚细胞定位
Mitochondrion membrane.
组织特异性
Expressed in a wide variety of tissues.
相似性
Belongs to the Bcl-2 family.
功能
In the presence of an appropriate stimulus, accelerates programmed cell death by binding to, and antagonizing the anti-apoptotic action of BCL2 or its adenovirus homolog E1B 19k protein. Low micromolar levels of zinc ions inhibit the promotion of apoptosis.
