Abstract
COP/DET/FUS (Constituitive photomorphogensis/De-etiolated/Fusca) proteins negatively regulate photomorphogensis in plants. Recently, they were revealed to degrade some transcription factors, which were positive regulators of photomorphogeneis. In this work, we focus on the proteolysis through a COP/DET/FUS protein, COP10. COP10 composes of CDD complex together with UV-damaged DNA binding protein 1 (DDB1) and De-etiolated 1 (DET1). In addition, CDD complex was found to interact with Cullin4 and Rbx1. Here, we show the results of novel interacting factors with CDD core complex.
