Abstract excerpt
CONSTITUTIVELY PHOTOMORPHOGENIC1 (COP1) possesses E3 ligase activity and promotes degradation of key factors involved in the light regulation of plant development. The finding that CULLIN4 (CUL4)-Damaged DNA Binding Protein1 (DDB1) interacts with DDB1 binding WD40 (DWD) proteins to act as E3 ligases implied that CUL4-DDB1 may associate with COP1-SUPPRESSOR OF PHYA (SPA) protein complexes, since COP1 and SPAs are...
