A phyB-PIF1-SPA1 kinase regulatory complex promotes photomorphogenesis in Arabidopsis (OA) (Nature Communications)
CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1) is one of the best characterized E3 ubiquitin ligases with broad roles as a central repressor of light signaling in plants to cancer biology in mammals. In plants, COP1 interacts with SUPPRESSOR OF PHYA-105 1 family members (SPA1-SPA4) and forms a stable COP1/SPA complex. Paik et al., provide evidence that SPA1, […]
