DomainIntact BH3 motif is 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.
FunctionThe major proteolytic product p15 BID allows the release of cytochrome c (By similarity). Isoform 1, isoform 2 and isoform 4 induce ICE-like proteases and apoptosis. Isoform 3 does not induce apoptosis. Counters the protective effect of Bcl-2. {ECO:0000250, ECO:0000269|PubMed:14583606}.

Ptmp15 BID is ubiquitinated by ITCH; ubiquitination results in proteasome-dependent degradation. {ECO:0000269|PubMed:20392206}.
PtmTNF-alpha induces a caspase-mediated cleavage of p22 BID into a major p15 and minor p13 and p11 products. {ECO:0000250}.
Sequence CautionSequence=AAH22072.2; Type=Erroneous initiation; Evidence={ECO:0000305};
Subcellular LocationBH3-interacting domain death agonist p13: Mitochondrion membrane {ECO:0000250}. Note=Associated with the mitochondrial membrane. {ECO:0000250}.
Subcellular LocationBH3-interacting domain death agonist p15: Mitochondrion membrane {ECO:0000250}. Note=Translocates to mitochondria as an integral membrane protein. {ECO:0000250}.
Subcellular LocationCytoplasm {ECO:0000250}. Mitochondrion membrane {ECO:0000250}. Note=When uncleaved, it is predominantly cytoplasmic. {ECO:0000269|PubMed:14583606}.
Subcellular LocationIsoform 1: Cytoplasm.
Subcellular LocationIsoform 2: Mitochondrion membrane. Note=A significant proportion of isoform 2 localizes to mitochondria, it may be cleaved constitutively.
Subcellular LocationIsoform 3: Cytoplasm.
SubunitForms heterodimers either with the pro-apoptotic protein BAX or the anti-apoptotic protein Bcl-2 (By similarity). p15 BID interacts with ITCH. {ECO:0000250, ECO:0000269|PubMed:20392206}.
Tissue SpecificityIsoform 2 and isoform 3 are expressed in spleen, bone marrow, cerebral and cerebellar cortex. Isoform 2 is expressed in spleen, pancreas and placenta (at protein level). Isoform 3 is expressed in lung, pancreas and spleen (at protein level). Isoform 4 is expressed in lung and pancreas (at protein level). {ECO:0000269|PubMed:14583606}.
