CC   -!- FUNCTION: Transcription factor that promotes photomorphogenesis in the
CC       light and positively regulates fruit pigmentation and fruit nutritional
CC       quality. Probably acts downstream of the light receptor network and
CC       directly affects transcription of light-induced genes.
CC       {ECO:0000269|PubMed:15178762}.
CC   -!- SUBUNIT: Interacts with COP1.
CC   -!- SUBCELLULAR LOCATION: Nucleus.
CC   -!- PTM: Ubiquitinated by COP1. Ubiquitination takes place in darkness and
CC       leads to its subsequent degradation, thereby preventing to activate
CC       photomorphogenesis signals (By similarity). {ECO:0000250}.
CC   -!- MISCELLANEOUS: When it is down-regulated, plants exhibit defects in
CC       light responses, including inhibited seedling photomorphogenesis, loss
CC       of thylakoid organization, and reduced carotenoid accumulation.
CC   -!- SIMILARITY: Belongs to the bZIP family. {ECO:0000305}.
