Source	Description
UniProt	Transcription activator that acts as positive regulator of seedling photomorphogenesis (PubMed:17965270). Acts downstream of COP1 and play an important role in early and long-term adjustment of the shade avoidance syndrome (SAS) responses in natural environments (PubMed:21070414). {ECO:0000269\|PubMed:17965270, ECO:0000269\|PubMed:21070414}.
