BNIP3L (Nix) is a mitochondrial protein that homodimerizes, is localized to mitochondria via its C-terminal transmembrane domain, interacts with anti-apoptotic proteins Bcl-2 and Bcl-xL, and induces apoptosis; both the BH3 domain and the transmembrane/membrane-anchoring domain are required for cell death induction; recombinant BNIP3L added to isolated mitochondria induces membrane potential loss and cytochrome c release. |

Nix and Nip3 form a pro-apoptotic mitochondrial protein subfamily; Nix colocalizes with mitochondrial HSP60, homodimerizes (expressed as ~48 kDa dimer from 23.8 kDa monomer), undergoes proteasomal degradation to an 11 kDa C-terminal fragment, and its transmembrane domain is required for mitochondrial localization and apoptosis induction; Nix can overcome Bcl-2 and Bcl-xL but high Bcl-xL levels inhibit its apoptotic activity. |
