BOK (BCL2 Family Ovarian Killer) is a pro-apoptotic member of the BCL2 protein family that plays a critical role in regulating mitochondrial apoptosis. Located primarily on the endoplasmic reticulum (ER) and mitochondria, BOK contains BH1, BH2, and BH3 domains and functions as a potent inducer of programmed cell death. Unlike its close homologs BAX and BAK1, BOK exhibits constitutive pro-apoptotic activity and can be directly inhibited by anti-apoptotic proteins such as MCL1 and BCL2. In the nervous system, BOK may contribute to neuronal apoptosis under ER stress conditions, making it relevant to neurodegenerative disease research.
BOK (BCL2 Family Ovarian Killer) is a pro-apoptotic BCL2 family protein with BH1, BH2, and BH3 domains. Unlike BAX and BAK1, BOK is constitutively active and localized to the endoplasmic reticulum (ER) and mitochondria. It promotes apoptosis by inducing ER calcium release and mitochondrial dysfunction. BOK can be inhibited by MCL1 and other anti-apoptotic proteins. Its physiological function is less characterized than BAX and BAK1, but it plays roles in apoptosis induced by ER stress and other stimuli.
BOK is expressed in many tissues with high expression in ovary. In brain, it is expressed at lower levels in neurons and may contribute to neuronal apoptosis under stress conditions.
| Disease | Variants | Inheritance | Mechanism |
|---|---|---|---|
| Neurodegeneration | May contribute | Acquired | ER stress-induced apoptosis |
| Cancer | Often downregulated | Somatic | Tumor suppression |
