Function
Transcriptional coactivator necessary for expression of the clock genes PRR5 and TOC1 (PubMed:25012192, PubMed:25848708). Antagonizes REV8 function in the regulation of anthocyanin accumulation (PubMed:25848001). Involved in red light input to the clock (PubMed:25012192). Activates clock-controlled genes with afternoon peak (PubMed:23818596). Mediates light inhibition of hypocotyl elongation (PubMed:23818596). Unable to bind to DNA, but recruited to the evening element (EE)-containing region of the PRR5 and TOC1 promoters through its interaction with the DNA binding proteins REV8 and REV4 (PubMed:25012192, PubMed:25848708).
