Anti-BCL2 like 2 antibodies are used for the immunodetection of the protein encoded by the BCL2L2 gene. In humans, the canonical protein has a reported length of 193 amino acid residues and a mass of 20.7 kDa. Its subcellular localization is in the mitochondria and membrane. Alternative splicing is reported to yield 2 different isoforms for this protein. It is reported to be expressed in a wide range of tissues with highest levels in the brain, spinal cord, testis, pancreas, heart, spleen and mammary glands. A member of the Bcl-2 protein family, it is reported to promote cell survival. Other names for this target antigen include BCLW, PPP1R51, bcl-2-like protein 2, apoptosis regulator BCL-W, protein phosphatase 1, regulatory subunit 51, and BCL-W. Gene orthologs have been identified in the mouse, rat and bovine species. Over 60 citations in the literature describe the use of BCL2 like 2 antibodies in research. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
