Predicted to enable cysteine-type endopeptidase inhibitor activity and ubiquitin conjugating enzyme activity. Predicted to be involved in negative regulation of apoptotic process and positive regulation of apoptotic process. Predicted to act upstream of or within ubiquitin-dependent protein catabolic process. Predicted to be located in cytosol and nucleoplasm. Predicted to be active in nucleus. Orthologous to human UBE2Z (ubiquitin conjugating enzyme E2 Z). [provided by Alliance of Genome Resources, Apr 2022]
