Bcl-2 Blocking Peptide (Center Ser70) Blocking Peptide

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. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

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.
