Source Description
TAIREncodes a MYB family transcription factor Circadian 1 (CIR1). Involved in circadian regulation in Arabidopsis.
UniProtPositive regulator for cold-responsive gene expression and cold tolerance. Part of a regulatory feedback loop that controls a subset of the circadian outputs and modulates the central oscillator. Negatively self-regulates its own expression. {ECO:0000269|PubMed:17587236, ECO:0000269|PubMed:23371945}.
