OX NCBI_TaxID=9615; RN [1] RP NUCLEOTIDE SEQUENCE [MRNA]. RA Chien M.B., London C.A., Jones C.S.; RL Submitted (DEC-2003) to the EMBL/GenBank/DDBJ databases. CC -!- FUNCTION: Suppresses apoptosis in a variety of cell systems CC including factor-dependent lymphohematopoietic and neural cells. CC Regulates cell death by controlling the mitochondrial membrane CC permeability. Appears to function in a feedback loop system with CC caspases. Inhibits caspase activity either by preventing the CC release of cytochrome c from the mitochondria and/or by binding to CC the apoptosis-activating factor (APAF-1) (By similarity). CC -!- SUBUNIT: Forms homodimers, and heterodimers with BAX, BAD, BAK and CC Bcl-X(L). Heterodimerization with BAX requires intact BH1 and BH2 CC motifs, and is necessary for anti-apoptotic activity (By CC similarity). Also interacts with APAF1, BBC3, BCL2L1, BNIPL, EI24, CC MRPL41 and TP53BP2. Binding to FKBP8 seems to target BCL2 to the CC mitochondria and probably interferes with the binding of BCL2 to CC its targets. Interacts with BAG1 in an ATP-dependent manner. CC Interacts with RAF1 (the 'Ser-338' and 'Ser-339' phosphorylated CC form). Interacts (via the BH4 domain) with EGLN3; the interaction CC prevents the formation of the BAX-BCL2 complex and inhibits the CC anti-apoptotic activity of BCL2 (By similarity). Interacts with CC G0S2; this interaction also prevents the formation of the anti- CC apoptotic BAX-BCL2 complex (By similarity). CC -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane; Single-pass CC membrane protein (By similarity). Nucleus membrane; Single-pass CC membrane protein (By similarity). Endoplasmic reticulum membrane; CC Single-pass membrane protein (By similarity). CC -!- DOMAIN: The BH4 motif is required for anti-apoptotic activity and CC for interaction with RAF1 and EGLN3 (By similarity). CC -!- PTM: Phosphorylation/dephosphorylation on Ser-70 regulates anti- CC apoptotic activity. Growth factor-stimulated phosphorylation on CC Ser-70 by PKC is required for the anti-apoptosis activity and CC occurs during the G2/M phase of the cell cycle (By similarity). In CC the absence of growth factors, BCL2 appears to be phosphorylated CC by other protein kinases such as ERKs and stress-activated kinases CC (By similarity). Phosphorylated by MAPK8/JNK1 at Thr-69, Ser-70 CC and Ser-84, wich stimulates starvation-induced autophagy (By CC similarity). Dephosphorylated by protein phosphatase 2A (PP2A) (By CC similarity). CC -!- PTM: Proteolytically cleaved by caspases during apoptosis. The CC cleaved protein, lacking the BH4 motif, has pro-apoptotic CC activity, causes the release of cytochrome c into the cytosol CC promoting further caspase activity (By similarity). CC -!- PTM: Monoubiquitinated by PARK2, leading to increase its stability CC (By similarity). CC -!- SIMILARITY: Belongs to the Bcl-2 family.
