Baculoviral IAP repeat-containing protein 6 is a protein that in humans is encoded by the BIRC6 gene.[1][2]


This gene encodes a protein with a BIR (baculoviral inhibition of apoptosis protein repeat) domain and a UBCc (ubiquitin-conjugating enzyme E2, catalytic) domain. This protein inhibits apoptosis by facilitating the degradation of apoptotic proteins by ubiquitination.[2]


BIRC6 has been shown to interact with KIF23.[3]


BIRC6 is implicated in leukemia, melanoma, breast cancer, lung cancer, colorectal cancer, and other cancers [4] (see the Atlas of Genetics and Cytogenetics in Oncology and Haematology,[5]).
