Application Abreviews Notes
WB 1/1000. Predicted molecular weight: 37 kDa.
ICC/IF 1/100 - 1/500.


  • Function
    Involved in the regulation of apoptosis versus cell survival, and in the maintenance of viability but not of proliferation. Mediates its effects by interactions with a number of other regulators of apoptosis. Isoform 1 inhibits apoptosis. Isoform 2 promotes apoptosis.
  • Sequence similarities
    Belongs to the Bcl-2 family.
  • Post-translational
    Cleaved by CASP3 during apoptosis. In intact cells cleavage occurs preferentially after Asp-127, yielding a pro-apoptotic 28 kDa C-terminal fragment.
    Rapidly degraded in the absence of phosphorylation on Thr-163 in the PEST region.
    Phosphorylated on Thr-163. Treatment with taxol or okadaic acid induces phosphorylation on additional sites.
  • Cellular localization
    Membrane. Cytoplasm. Mitochondrion. Nucleus > nucleoplasm. Cytoplasmic, associated with mitochondria.
