Promotion of photomorphogenesis by COP1

Plant Molecular Biology, 2004
CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1) represses photomorphogenesis in darkness by targeting nuclear-localized transcription factors to proteasome-mediated degradation. Upon light exposure, COP1 migrates to the cytosol allowing photomorphogenesis to proceed but the residual nuclear pool down-regulates light signaling mediated by phytochrome A.

Dissecting the functions of COP1 in the UVR8 pathway with a COP1 variant in Arabidopsis

The Plant Journal, 2022
SUMMARYCOP1 is a critical repressor of plant photomorphogenesis in darkness. However, COP1 plays distinct roles in the photoreceptor UVR8 pathway in Arabidopsis thaliana. COP1 interacts with ultraviolet B (UV‐B)‐activated UVR8 monomers and promotes their retention and accumulation in the nucleus.

Spotlight on the role of COP1 in tumorigenesis

Nature Reviews Cancer, 2012
COP1 is an E3 ubiquitin ligase that is involved in the ubiquitylation of various protein substrates to trigger their proteasomal degradation. Although originally identified in a light signalling pathway in plants, biochemical studies have identified putative targets of mammalian COP1 with relevant roles in tumorigenesis, including the oncoproteins JUN ...
