UniProt data
UniProt name: BNI3L_HUMAN (O60238)
Gene name: BNIP3L; Synonyms=BNIP3A, BNIP3H, NIX
Organism: Homo sapiens (Human).
Function: Induces apoptosis. Interacts with viral and cellular anti-apoptosis proteins. Can overcome the suppressors BCL-2 and BCL-XL, although high levels of BCL-XL expression will inhibit apoptosis. Inhibits apoptosis induced by BNIP3. Involved in mitochondrial quality control via its interaction with SPATA18/MIEAP: in response to mitochondrial damage, participates in mitochondrial protein catabolic process (also named MALM) leading to the degradation of damaged proteins inside mitochondria. The physical interaction of SPATA18/MIEAP, BNIP3 and BNIP3L/NIX at the mitochondrial outer membrane regulates the opening of a pore in the mitochondrial double membrane in order to mediate the translocation of lysosomal proteins from the cytoplasm to the mitochondrial matrix. May function as a tumor suppressor. {ECO:0000269|PubMed:10381623, ECO:0000269|PubMed:21264228}.
Subcellular location: Nucleus envelope. Endoplasmic reticulum. Mitochondrion outer membrane. Membrane {ECO:0000305}; Single-pass membrane protein {ECO:0000305}. Note=Colocalizes with SPATA18 at the mitochondrion outer membrane.
Transmembrane domains:
- 188-208, 21 AA, Helical. {ECO:0000255}.
Sequence: 219 AA
