PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • one Bcl-2 homology 3 (BH3) domain, required by BIK, BID, BAK, BAD and BAX for their pro-apoptotic activity and for their interaction with anti-apoptotic members of the BCL-2 family
  • three phosphorylation sites Ser 75, Ser 99, Ser 118
  • secondary structure an helix
    mono polymer heteromer , dimer
    HOMOLOGY
    interspecies homolog to rattus Bad (77.8pc)
    homolog to murine Bad (77.8pc)

    basic FUNCTION
  • involved in positive regulation of cell apoptosis by protein-binding activity
  • involved in cytokine-dependent survival pathways
  • promoting cell death, and acting as a link between growth factor receptor signaling and the apoptotic pathways
  • having bifunctional activities in both beta cell survival and insulin secretion, and regulating the physiologic adaptation of beta cell mass during high-fat feeding
  • mediator of tuberin effects on the regulation of apoptosis
  • may be involved in glucose metabolism
  • pro-apoptotic BCL2 family protein that plays a critical role in the regulation of apoptotic response
  • CELLULAR PROCESS cell cycle
    cell life, cell death/apoptosis
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component
  • heterodimerizing with Bcl2, BCLXL, BCLW
  • pore forming activity upon phosphorylation
  • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • binding to TWHalpha proteins (ser 7S-ser99 phosphorylated form)
  • binding to S100A10 protein
  • regulated by heat shock proteins and the ubiquitin-poteasome pathway
  • interacting with PIM3 (can inactivate BAD by phosphorylating its Ser(112) in colon cancer cells and thus may prevent apoptosis and promote progression of colon cancer)
  • cell & other
    REGULATION
    activated by Ca2+ calmodulin
    TSC2
    inhibited by phosphorylation by Raf-1
    phospharylation at Ser 118 by CAPK (protein kinase A)
    phosphorylation by RSK-MAP kinase pathway
    phosphorylated by PIM2 on serine 112, which accounts in part for its ability to reverse Bad-induced cell death
    repressed by PI3 kinases pathway
