Arabidopsis COP10 is a ubiquitin-conjugating enzyme variant that acts together with COP1 and the COP9 signalosome in repressing photomorphogenesis.


A group of evolutionarily conserved pleiotropic COP/DET/FUS proteins was initially defined by their ability to repress photomorphogenesis in Arabidopsis. It was proposed that this regulation be mediated by targeting degradation of key cellular regulators that promote photomorphogenesis. Among them, COP1 and the COP9 signalosome have been hypothesized to… (More)
