CC -!- FUNCTION: Probable transcription factor that promotes early floral CC meristem identity in synergy with LEAFY. Is required subsequently CC for the transition of an inflorescence meristem into a floral CC meristem. Is indispensable for normal development of sepals and CC petals in the wild-type flower. Regulates positively the B class CC homeotic proteins APETALA3 and PISTILLATA with the cooperation of CC LEAFY and UFO. Interacts with SEPALLATA3 or AP3/PI heterodimer to CC form complexes that could be involved in genes regulation during CC floral meristem development. Regulates positively AGAMOUS in CC cooperation with LEAFY. Displays a redundant function with CC CAULIFLOWER in the up-regulation of LEAFY. CC -!- SUBUNIT: Homodimer capable of binding to CArG-box sequences. CC Heterodimer with SEP3. Binds AP3/PI to form a ternary complex.

CC -!- TISSUE SPECIFICITY: Expressed in young flower primordia, later CC becomes localized to sepals and petals. CC -!- DEVELOPMENTAL STAGE: Expressed at an early stage of floral CC initiation. CC -!- INDUCTION: Negatively regulated by TFL1 and by the C class floral CC homeotic protein AGAMOUS. Positively regulated by CAULIFLOWER. CC -!- MISCELLANEOUS: Mutations in the AP1 gene result in the partial CC conversion of flowers into shoots and a disruption of sepal and CC petal development. CC -!- SIMILARITY: Contains 1 K-box domain. CC -!- SIMILARITY: Contains 1 MADS-box domain.
