Function

Anti-apoptotic protein which can regulate cell death by controlling caspases and by acting as an E3 ubiquitin-protein ligase. Has an unusual ubiquitin conjugation system in that it could combine in a single polypeptide, ubiquitin conjugating (E2) with ubiquitin ligase (E3) activity, forming a chimeric E2/E3 ubiquitin ligase. Its tragets include CASP9 and DIABLO/SMAC. Acts as an inhibitor of CASP3, CASP7 and CASP9. Important regulator for the final stages of cytokinesis. Crucial for normal vesicle targeting to the site of abscission, but also for the integrity of the midbody and the midbody ring, and its striking ubiquitin modification. Required for normal placenta development. {ECO:0000269PubMed:15300255, ECO:0000269PubMed:15485903, ECO:0000269PubMed:9628897}.

Subcellular Localization

Golgi apparatus, trans-Golgi network membrane {ECO:0000250}. Midbody {ECO:0000250}. Endosome {ECO:0000250}. Cytoplasm, cytoskeleton, spindle pole {ECO:0000250}. Cytoplasm, cytoskeleton, microtubule organizing center, centrosome {ECO:0000250}. Note=Concentrates in a pericentriolar compartment in interphase, moves partially to spindle poles in metaphase, and finally localizes to the spindle midzone and the midbody in telophase and during cytokinesis. {ECO:0000250}.

Disease Associations

Tissue Specificity

Widely expressed. Highly expressed in the brain and kidney. {ECO:0000269PubMed:9628897}.
