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). May attenuate
CC       inflammation by impairing NLRP1-inflammasome activation, hence
CC       CASP1 activation and IL1B release (By similarity).
CC       {ECO:0000250|UniProtKB:P10415}.
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. Also
CC       interacts with APAF1, BBC3, BCL2L1, BNIPL, EI24, FKBP8, MRPL41,
CC       and TP53BP2. 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). Interacts with BOP (By
CC       similarity). Interacts with the SCF(FBXO10) complex (By
CC       similarity). Interacts (via the loop between motifs BH4 and BH3)
CC       with NLRP1 (via LRR repeats) (By similarity). {ECO:0000250,
CC       ECO:0000250|UniProtKB:P10415}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion outer membrane; Single-pass
CC       membrane protein. Nucleus membrane; Single-pass membrane protein.
CC       Endoplasmic reticulum membrane; Single-pass membrane protein.
CC   -!- TISSUE SPECIFICITY: Expressed in a variety of tissues, with
CC       highest levels in reproductive tissues. In the adult brain,
CC       expression is localized in mitral cells of the olfactory bulb,
CC       granule and pyramidal neurons of hippocampus, pontine nuclei,
CC       cerebellar granule neurons, and in ependymal cells. In prenatal
CC       brain, expression is higher and localized in the neuroepithelium
CC       and in the cortical plate.
CC   -!- DOMAIN: The BH4 motif is required for anti-apoptotic activity and
CC       for interaction with RAF1 and EGLN3. {ECO:0000250}.
CC   -!- DOMAIN: BH1 and BH2 domains are required for the interaction with
CC       BAX and for anti-apoptotic activity.
CC       {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   -!- 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. In the absence of
CC       growth factors, BCL2 appears to be phosphorylated by other protein
CC       kinases such as ERKs and stress-activated kinases. Phosphorylated
CC       by MAPK8/JNK1 at Thr-69, Ser-70 and Ser-84, wich stimulates
CC       starvation-induced autophagy (By similarity). Dephosphorylated by
CC       protein phosphatase 2A (PP2A) (By similarity). {ECO:0000250}.
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). {ECO:0000250}.
CC   -!- PTM: Monoubiquitinated by PRKN, leading to increase its stability.
CC       Ubiquitinated by SCF(FBXO10), leading to its degradation by the
CC       proteasome. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the Bcl-2 family. {ECO:0000305}.
