COP1 E3 ligase protects HYL1 to retain microRNA biogenesis

Figure 3: HYL1 is a short-lived protein and highly unstable but not in ubiquitin–proteasome pathway. In summary, our findings not only revealed the duplicity of COP1—a protector by day and a ...

Convergence of light and chloroplast signals for de-etiolation through ABI4–HY5 and COP1

Seedling de-etiolation prepares plants to switch from heterotrophic to photoautotrophic growth, a transition essential for plant survival. This delicate de-etiolation process is precisely controlled ...

Expression of an N-Terminal Fragment of COP1 Confers a Dominant-Negative Effect on Light-Regulated Seedling Development in Arabidopsis

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 ...
