Direct interaction of Arabidopsis cryptochromes with COP1 in light control development.

Science (New York, N.Y.) - 5 Oct 2001

Wang H, Ma L G, Li J M, Zhao H Y, Deng X W

Abstract excerpt

Arabidopsis seedling photomorphogenesis involves two antagonistically acting components, COP1 and HY5. COP1 specifically targets HY5 for degradation via the 26S proteasome in the dark through their direct physical interaction. Little is known regarding how light signals perceived by photoreceptors are transduced to regulate COP1. Arabidopsis has two related cryptochromes (cry1 and cry2) mediating various...
