CC -!- FUNCTION: Transcription factor that promotes early floral meristem CC identity in synergy with LEAFY. Is required subsequently for the CC transition of an inflorescence meristem into a floral meristem. Is CC indispensable for normal development of sepals and petals in CC flowers. Regulates positively the B class homeotic proteins CC APETALA3 and PISTILLATA with the cooperation of LEAFY and UFO. CC Interacts with SEPALLATA3 or AP3/PI heterodimer to form complexes CC that could be involved in genes regulation during floral meristem CC development. Regulates positively AGAMOUS in cooperation with CC LEAFY. Displays a redundant function with CAULIFLOWER in the up- CC regulation of LEAFY. Together with AGL24 and SVP, controls the CC identity of the floral meristem and regulates expression of class CC B, C and E genes. Represses flowering time genes AGL24, SVP and CC SOC1 in emerging floral meristems. {ECO:0000269|PubMed:11283333, CC ECO:0000269|PubMed:17428825, ECO:0000269|PubMed:17794879, CC ECO:0000269|PubMed:19656343, ECO:0000269|Ref.8}. CC -!- SUBUNIT: Homodimer capable of binding to CArG-box sequences. CC Heterodimer with SEP3, AP1 and SVP. Binds AP3/PI to form a ternary CC complex. Interacts with the SEU-LUG corepressor complex when CC complexed to AGL24 or SVP. Interacts with AGL15 and AGL16. CC {ECO:0000269|PubMed:15805477, ECO:0000269|PubMed:16679456}.

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.
