UniProt Comments
Transcriptional regulator involved in the specification of floral identity. Acts as A class cadastral protein by repressing the C class floral homeotic gene AGAMOUS in the external flower organs in association with APETALA2 and other repressors. Is required to maintain floral meristem identity in concert with AGAMOUS. Interacts also with APETALA2 to ensure the normal development of ovule.
