Is predicted to encode a protein with the following domains: Winged helix DNA-binding domain superfamily; Brf1-like TBP-binding domain; Cullin protein, neddylation domain; Brf1, TBP-binding domain; Cullin-4B; Cullin protein neddylation domain; and Winged helix-like DNA-binding domain superfamily. Is an ortholog of C. elegans
cul-4. In C. elegans,
cul-4 is involved in proteasome-mediated ubiquitin-dependent protein catabolic process.
