Transcription factor that functions as a repressor of flowering by enhancing the expression of several genes that delay flowering including FLC, FLM/MAF1, MAF2 and SVP. Also acts in the floral homeotic AGAMOUS (AG) pathway, specifically by processing the AGAMOUS pre-mRNA. Functions in association with HUA1 and HEN4 in AG pre-mRNA processing. Involved in all three aspects of the AG functions, the specification of stamen and carpel identities, the control of floral determinacy, and the spatial restriction of AP1 expression. Acts as a transcription regulator that controls anthocyanin accumulation
