Members of the Bcl-2 family of proteins regulate cell survival by either inhibiting apoptosis or by facilitating the complicated process of cell death. Bcl-B, also known as BCL2L10, Diva, Boo or BCLB, is a widely expressed 194 amino acid member of the Bcl-2 protein family. Localized to the nuclear membrane, Bcl-B promotes cell survival by suppressing BAX-induced apoptosis. Bcl-2 contains a BH4 domain as well as a transmembrane domain, both of which are necessary for its antiapoptotic effects. Overexpression of Bcl-B is thought to prevent the release of cytochrome C from the mitochondria, thereby triggering caspase-3 activation and suppressing cell apoptosis. Bcl-B is implicated in the pathogenesis of cervical cancer. |
