NCBI Protein Information
COP1-interacting protein 8
NCBI Summary
Encodes a RING-H2 protein that interacts with the RING finger domain of COP1. CIP8 exhibits a strong interaction with the E2 ubiquitin conjugating enzyme AtUBC8 through its N-terminal domain and promotes ubiquitination in an E2-dependent fashion in vitro. It is possible that the AtUBC8-CIP8 module might interact with COP1 in vivo, thereby participating in proteasome-mediated degradation of HY5.

UniProt Comments
E3 ubiquitin-protein ligase that mediates ubiquitination and subsequent proteasomal degradation of target proteins. Probably forms a minimal ubiquitin ligase complex in cooperation with the E2 enzyme UBC8. Its interaction with COP1 suggests that it may participate in proteasome-mediated degradation of HY5 in vivo.
