B-Cell Lymphoma Protein 2 Alpha (BCL2) Human Recombinant Protein

This gene encodes an integral outer mitochondrial membrane protein that blocks the apoptotic death of some cells such as lymphocytes. Constitutive expression of BCL2, such as in the case of translocation of BCL2 to Ig heavy chain locus, is thought to be the cause of follicular lymphoma. Two transcript variants, produced by alternate splicing, differ in their C-terminal ends. [provided by RefSeq, Jul 2008]

Bcl-2: a antiapoptotic member of the Bcl-2 family. Regulates cell death by controlling the mitochondrial membrane permeability. Inhibits caspase activity either by preventing the release of cytochrome c from the mitochondria and/or by binding to the apoptosis-activating factor (APAF-1). Phosphorylation by JNKs may increase its antiapoptotic functions.
