Predicted to enable several functions, including FBXO family protein binding activity; chaperone binding activity; and cysteine-type endopeptidase inhibitor activity involved in apoptotic process. Involved in response to cAMP; response to ethanol; and response to hypoxia. Located in XY body; membrane raft; and nucleus. Part of protein-containing complex. Human ortholog(s) of this gene implicated in breast cancer. Orthologous to human BIRC2 (baculoviral IAP repeat containing 2). [provided by Alliance of Genome Resources, Apr 2022]
