CC -!- FUNCTION: Essential mediator of p53/TP53-dependent and p53/TP53-
CC independent apoptosis (PubMed:11463391, PubMed:23340338). Promotes
CC partial unfolding of BCL2L1 and dissociation of BCL2L1 from p53/TP53,
CC releasing the bound p53/TP53 to induce apoptosis (PubMed:23340338).
CC Regulates ER stress-induced neuronal apoptosis (By similarity).
CC {ECO:0000250|UniProtKB:Q99ML1, ECO:0000269|PubMed:11463391,
CC ECO:0000269|PubMed:23340338}.
CC -!- SUBUNIT: Interacts with MCL1 and BCL2A1 (By similarity). Interacts (via
CC BH3 domain) with BCL2 (PubMed:11463391). Interacts with BCL2L1/BCL-XL
CC (PubMed:23340338). Interacts (via BH3 domain) with NOL3/ARC (via CARD
CC domain); this interaction prevents BBC3 association with BCL2 and
CC results in CASP8 activation (By similarity).

CC {ECO:0000269|PubMed:11463391}.
CC -!- INDUCTION: Up-regulated by TP53 (PubMed:11463392, PubMed:11572983). Up-
CC regulated by DNA damage, glucocorticoid treatment and growth factor
CC deprivation (PubMed:11572983). Up-regulated by ER stress in a
CC DDIT3/CHOP-dependent manner (PubMed:22761832).
CC {ECO:0000269|PubMed:11463392, ECO:0000269|PubMed:11572983,
CC ECO:0000269|PubMed:22761832}.
CC -!- DOMAIN: The BH3 motif is intrinsically disordered in the absence of a
CC binding partner but folds upon binding (PubMed:23340338). Folds when
CC bound to BCL2L1 (PubMed:23340338). Also folds when bound to MCL1 (By
CC similarity). {ECO:0000250|UniProtKB:Q99ML1,
CC ECO:0000269|PubMed:23340338}.
CC -!- SIMILARITY: Belongs to the Bcl-2 family. {ECO:0000305}.
