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
