Bcl-2-like protein 2 is a protein that in humans is encoded by the BCL2L2 gene. This gene encodes a pro-survival (anti-apoptotic) member of the bcl-2 protein family. The proteins of this family form hetero- or homodimers and act as anti- and pro-apoptotic regulators. Expression of this gene in cells has been shown to contribute to reduced cell apoptosis under cytotoxic conditions.
