Predicted to enable anaphase-promoting complex binding activity and ubiquitin ligase activator activity. Predicted to be involved in several processes, including anaphase-promoting complex-dependent catabolic process; negative regulation of cell cycle process; and positive regulation of cellular protein metabolic process. Predicted to act upstream of or within lens fiber cell differentiation; proteolysis involved in cellular protein catabolic process; and regulation of meiotic nuclear division. Predicted to be located in nuclear membrane and nucleoplasm. Predicted to be part of anaphase-promoting complex. Orthologous to human FZR1 (fizzy and cell division cycle 20 related 1).
