Predicted to enable anaphase-promoting complex binding activity and ubiquitin conjugating enzyme activity. Predicted to contribute to ubiquitin-protein transferase activity. Predicted to be involved in several processes, including anaphase-promoting complex-dependent catabolic process; free ubiquitin chain polymerization; and protein polyubiquitination. Predicted to act upstream of or within protein K11-linked ubiquitination. Predicted to be part of anaphase-promoting complex. Predicted to be active in nucleus. Orthologous to human UBE2S (ubiquitin conjugating enzyme E2 S). [provided by Alliance of Genome Resources, Apr 2022]
