Predicted to enable ubiquitin protein ligase binding activity. Predicted to be involved in ubiquitin-dependent protein catabolic process. Is an ortholog of C. elegans
cul-2. In C. elegans,
cul-2 is involved in several processes, including anaphase-promoting complex-dependent catabolic process; positive regulation of metaphase/anaphase transition of meiotic cell cycle; and reproductive process.
