Enables cullin family protein binding activity and ubiquitin protein ligase activity. Involved in lipid storage and protein ubiquitination. Part of Cul3-RING ubiquitin ligase complex. Is expressed in organism and wing disc.
FB Description
Regulator of cullins 1b (Roc1b) encodes a C2H2 type zinc finger protein that binds specifically to the product of Cul3 and recruits ubiquitin-charged E2 to the CRL3 E3 ubiquitin ligase complex, which functions during spermatogenesis.
