Regulation of Arabidopsis photoreceptor CRY2 by two distinct E3 ubiquitin ligases

Abstract

The fate of proteins in cells is determined by not only synthesis but also degradation. Here Chen et al. show that degradation of the plant blue light receptor CRY2 is determined by two distinct E3 ubiquitin ligases, Cul4COP1/SPAs and Cul3LRBs, regulating the function of CRY2 under different light conditions.
