CC -!- FUNCTION: Suppresses apoptosis in a variety of cell systems including CC factor-dependent lymphohematopoietic and neural cells. Regulates cell CC death by controlling the mitochondrial membrane permeability. Appears CC to function in a feedback loop system with caspases. Inhibits caspase CC activity either by preventing the release of cytochrome c from the CC mitochondria and/or by binding to the apoptosis-activating factor CC (APAF-1). Also acts as an inhibitor of autophagy: interacts with BECN1 CC and AMBRA1 during non-starvation conditions and inhibits their CC autophagy function. May attenuate inflammation by impairing NLRP1- CC inflammasome activation, hence CASP1 activation and IL1B release. CC {ECO:0000250|UniProtKB:P10415}. CC -!- SUBUNIT: Forms homodimers, and heterodimers with BAX, BAD, BAK and Bcl- CC X(L). Heterodimerization with BAX requires intact BH1 and BH2 motifs, CC and is necessary for anti-apoptotic activity (By similarity). Component CC of the complex, at least composed of LRPPRC, BECN1 and BCL2; the CC interactions prevent BECN1 from forming an autophagy-inducing complex CC with PIK3C3 (By similarity). Interacts with EI24 (By similarity). Also CC interacts with APAF1, BBC3, BCL2L1, BNIPL, MRPL41 and TP53BP2. Binding CC to FKBP8 seems to target BCL2 to the mitochondria and probably CC interferes with the binding of BCL2 to its targets. Interacts with BAG1 CC in an ATP-dependent manner. Interacts with RAF1 (the 'Ser-338' and CC 'Ser-339' phosphorylated form). Interacts (via the BH4 domain) with CC EGLN3; the interaction prevents the formation of the BAX-BCL2 complex CC and inhibits the anti-apoptotic activity of BCL2. Interacts with G0S2; CC this interaction also prevents the formation of the anti-apoptotic BAX- CC BCL2 complex. Interacts with RTL10/BOP. Interacts with the SCF(FBXO10) CC complex. Interacts (via the loop between motifs BH4 and BH3) with NLRP1 CC (via LRR repeats), but not with NLRP2, NLRP3, NLRP4, PYCARD, nor MEFV CC (By similarity). Interacts with GIMAP3/IAN4, GIMAP4/IAN1 and CC GIMAP5/IAN5 (By similarity). Interacts with BCAP31. Interacts with CC IRF3; the interaction is inhibited by Sendai virus infection. Interacts CC with BECN1; thereby inhibiting autophagy in non-starvation conditions. CC Interacts with AMBRA1; thereby inhibiting autophagy (By similarity). CC {ECO:0000250|UniProtKB:P10415, ECO:0000250|UniProtKB:P10417}. CC -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane CC {ECO:0000250|UniProtKB:P10415}; Single-pass membrane protein CC {ECO:0000255}. Nucleus membrane {ECO:0000250|UniProtKB:P10415}; Single- CC pass membrane protein {ECO:0000255}. Endoplasmic reticulum membrane CC {ECO:0000250|UniProtKB:P10415}; Single-pass membrane protein CC {ECO:0000255}. Cytoplasm {ECO:0000250|UniProtKB:P10417}. CC -!- DOMAIN: The BH4 motif is required for anti-apoptotic activity and for CC interaction with RAF1 and EGLN3. {ECO:0000250}. CC -!- DOMAIN: BH1 and BH2 domains are required for the interaction with BAX CC and for anti-apoptotic activity. {ECO:0000250|UniProtKB:P10415}. CC -!- DOMAIN: The loop between motifs BH4 and BH3 is required for the CC interaction with NLRP1. {ECO:0000250|UniProtKB:P10415}. CC -!- DOMAIN: The BH3 motif is required for XIAP-mediated ubiquitination and CC subsequent induction of apoptosis. {ECO:0000250|UniProtKB:P10415}. CC -!- PTM: Phosphorylation/dephosphorylation on Ser-70 regulates anti- CC apoptotic activity. Growth factor-stimulated phosphorylation on Ser-70 CC by PKC is required for the anti-apoptosis activity and occurs during CC the G2/M phase of the cell cycle (By similarity). In the absence of CC growth factors, BCL2 appears to be phosphorylated by other protein CC kinases such as ERKs and stress-activated kinases (By similarity). CC Phosphorylated by MAPK8/JNK1 at Thr-69, Ser-70 and Ser-84, which CC stimulates starvation-induced autophagy (By similarity). CC Dephosphorylated by protein phosphatase 2A (PP2A) (By similarity). CC {ECO:0000250|UniProtKB:P10415, ECO:0000250|UniProtKB:P10417}. CC -!- PTM: Proteolytically cleaved by caspases during apoptosis. The cleaved CC protein, lacking the BH4 motif, has pro-apoptotic activity, causes the CC release of cytochrome c into the cytosol promoting further caspase CC activity (By similarity). {ECO:0000250|UniProtKB:P10415}. CC -!- PTM: Monoubiquitinated by PRKN, leading to an increase in its CC stability. Ubiquitinated by SCF(FBXO10), leading to its degradation by CC the proteasome. {ECO:0000250|UniProtKB:P10415}. CC -!- SIMILARITY: Belongs to the Bcl-2 family. {ECO:0000305}.
