A member of the Bcl-2 family of proteins, Bcl-xL is a potent anti-apoptotic protein located in the membrane of mitochondria. Presence of Bcl-xL prevents the mitochondrial membrane from becomming permeable by binding to and blocking the voltage-dependant anion channels (VDAC). This inhibits the release of the cytochrome C1, and prevents initiation of the caspase cascade and downstream apoptotic events. Bcl-xL can also directly bind to cytochrome C1 residues to prevent apoptosis. The overexpression of Bcl-xL can occur in certain cancers where increased expression can block or delay the onset of apoptosis. In certain cancers, Bcl-xL can also induce epithelial-mesenchymal transition and promote tumor angiogenesis.
