Preparation and Storage

  • Stability and Storage

    Shipped at 4°C. Store at +4°C short term (1-2 weeks). Upon delivery aliquot. Store at -20°C. Avoid freeze / thaw cycle.

    Preservative: None
    Constituents: 250mM Sodium chloride, 10mM Tris HCl, 1mM EDTA, pH 8

  • ReconstitutionSuspend in 100µl of 0.5M Acetic acid, over night at 4°C. Dilute 10 fold into selected buffer system. Bcl-2 has tendency to form intramolecular disulfide bond, 5mM DTT is recommended in assay buffer. Upon reconstitution ab73696 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Please prevent freeze-thaw cycles.

  • FunctionSuppresses apoptosis in a variety of cell systems including factor-dependent lymphohematopoietic and neural cells. Regulates cell death by controlling the mitochondrial membrane permeability. Appears to function in a feedback loop system with caspases. 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). May attenuate inflammation by impairing NLRP1-inflammasome activation, hence CASP1 activation and IL1B release (PubMed:17418785).
  • Tissue specificityExpressed in a variety of tissues.
  • Involvement in diseaseA chromosomal aberration involving BCL2 has been found in chronic lymphatic leukemia. Translocation t(14;18)(q32;q21) with immunoglobulin gene regions. BCL2 mutations found in non-Hodgkin lymphomas carrying the chromosomal translocation could be attributed to the Ig somatic hypermutation mechanism resulting in nucleotide transitions.
  • Sequence similaritiesBelongs to the Bcl-2 family.
  • DomainBH1 and BH2 domains are required for the interaction with BAX and for anti-apoptotic activity.
    The BH4 motif is required for anti-apoptotic activity and for interaction with RAF1 and EGLN3.
    The loop between motifs BH4 and BH3 is required for the interaction with NLRP1.
  • Post-translational
    modifications
    Phosphorylation/dephosphorylation on Ser-70 regulates anti-apoptotic activity. Growth factor-stimulated phosphorylation on Ser-70 by PKC is required for the anti-apoptosis activity and occurs during the G2/M phase of the cell cycle. In the absence of growth factors, BCL2 appears to be phosphorylated by other protein kinases such as ERKs and stress-activated kinases. Phosphorylated by MAPK8/JNK1 at Thr-69, Ser-70 and Ser-87, wich stimulates starvation-induced autophagy. Dephosphorylated by protein phosphatase 2A (PP2A).
    Proteolytically cleaved by caspases during apoptosis. The cleaved protein, lacking the BH4 motif, has pro-apoptotic activity, causes the release of cytochrome c into the cytosol promoting further caspase activity.
    Monoubiquitinated by PARK2, leading to increase its stability. Ubiquitinated by SCF(FBXO10), leading to its degradation by the proteasome.
  • Cellular localizationMitochondrion outer membrane. Nucleus membrane. Endoplasmic reticulum membrane.
