BNIP3

BNIP3
PFAM accession number:PF06553
Interpro abstract (IPR010548):

This family consists of several mammalian specific BCL2/adenovirus E1B 19kDa protein-interacting protein 3 or BNIP3 sequences. BNIP3 belongs to the Bcl-2 homology 3 (BH3)-only family, a Bcl-2-related family possessing an atypical Bcl-2 homology 3 (BH3) domain, which regulates PCD from mitochondrial sites by selective Bcl-2/Bcl-XL interactions. BNIP3 family members contain a C-terminal transmembrane domain that is required for their mitochondrial localisation, homodimerisation, as well as regulation of their pro-apoptotic activities. BNIP3-mediated apoptosis has been reported to be independent of caspase activation and cytochrome c release and is characterised by early plasma membrane and mitochondrial damage, prior to the appearance of chromatin condensation or DNA fragmentation [ (PUBMED:12690108) ].

GO process:positive regulation of apoptotic process (GO:0043065)
GO component:integral component of membrane (GO:0016021), mitochondrial envelope (GO:0005740)
