Expression of an N-terminal fragment of COP1 confers a dominant-negative effect on light-regulated seedling development in Arabidopsis.

The Plant cell - 1 Sept 1996

McNellis T W, Torii K U, Deng X W

Abstract excerpt

CONSTITUTIVE PHOTOMORPHOGENIC1 (COP1) is an essential regulatory gene that plays a role in light control of seedling development in Arabidopsis. The COP1 protein possesses three recognizable structural domains: a RING finger zinc binding domain near the N terminus, followed by a coiled-coll domain and a domain with WD-40 repeats in the C-terminal half. To determine whether COP1 acts specifically as a...
