Probable transcription factor that binds specifically to the CArG box DNA sequence 5'-CC (A/T)6 GG-3' (PubMed:7632923, PubMed:25183521). Plays an important role in the determination of flower meristem identity. Involved in the specification of sepal identity. Contributes to the development of petals, stamens and carpels (PubMed:15530395). Forms homodimers (PubMed:25183521). Interacts with TT16/AGL32 (PubMed:16080001). Expressed in aerial vegetative organs and flowers, but not in roots (PubMed:7632923). Expressed in flower primordia (PubMed:15530395).
