Predicted to enable cysteine-type endopeptidase inhibitor activity involved in apoptotic process and ubiquitin protein ligase activity. Acts upstream of or within lens development in camera-type eye. Predicted to be located in several cellular components, including Golgi apparatus; centrosome; and nucleoplasm. Predicted to be active in cytoplasm and nucleus. Is expressed in eye; lens; lens fiber; and lens vesicle. Orthologous to human BIRC7 (baculoviral IAP repeat containing 7). [provided by Alliance of Genome Resources, Apr 2022]
