Protein Information (annotations from UniProt)

Database IDHIV0000225
UniProt IDQ9BXH1
Primary gene name(s)BBC3
Synonym gene name(s)PUMA
Protein nameBcl-2-binding component 3
Protein functionEssential mediator of p53/TP53-dependent and p53/TP53-independent apoptosis. Functions by promoting partial unfolding of BCL2L1 and dissociation of BCL2L1 from p53/TP53. Regulates ER stress-induced neuronal apoptosis. {ECO:0000269|PubMed:11463391, ECO:0000269|PubMed:23340338}.
Subcellular locationMitochondrion {ECO:0000269|PubMed:11463391, ECO:0000269|PubMed:11463392, ECO:0000269|PubMed:11572983}. Note=Localized to the mitochondria in order to induce cytochrome c release.
