Probable transcription factor involved in the regulation of flowering time in long-day photoperiod. Participates in the repression of FT expression and floral transition, by interacting closely with the FLC-SVP pathways (PubMed:24876250). Functions in the satellite meristemoid lineage of stomatal development (PubMed:17704216). Homodimer. Interacts with AGL15, AGL24, AP1, AGL6, AG, AGL1, AGL11, AGL5, SEP3, SEP1, AGL63, AGL14, SOC1 and AGL21 (PubMed:15805477). Interacts with AGL63 (PubMed:20598091). Interacts with SVP (PubMed:24876250). Expressed at high levels in leaves, moderate levels in roots, seedlings and stems, and at low levels in flowers, pollen and siliques. Accumulates in leaf guard cells and trichomes. Also present in epidermal cells of roots (PubMed:11115127, PubMed:12837945, PubMed:12949148). Expressed in mature guard cells (PubMed:17704216). Repressed by the micro RNA miR824.
