Predicted to enable cysteine-type endopeptidase inhibitor activity and ubiquitin conjugating enzyme activity. Predicted to be involved in negative regulation of extrinsic apoptotic signaling pathway; placenta development; and regulation of cytokinesis. Predicted to act upstream of or within labyrinthine layer development; positive regulation of cell population proliferation; and spongiotrophoblast layer development. Predicted to be located in several cellular components, including microtubule cytoskeleton; midbody; and trans-Golgi network. Predicted to be active in nucleus. Orthologous to human BIRC6 (baculoviral IAP repeat containing 6). [provided by Alliance of Genome Resources, Apr 2022]
