Controls inflorescence meristem identity and is required for maintenance of an indeterminate inflorescence. Prevents the expression of 'APETALA1' and 'LEAFY'. Also plays a role in the regulation of the time of flowering in the long-day flowering pathway. May form complexes with phosphorylated ligands by interfering with kinases and their effectors (By similarity). Expressed below the apical dome of inflorescence and coflorescence meristems, and in inflorescence stem. Weakly expressed in vegetative phase from day 2 or day 3. Increased expression after commitment to flowering from day 7 on. Mutagenesis of His-88 to Tyr converts the repressor of flowering 'TERMINAL FLOWER 1' into a 'FLOWERING LOCUS T'-like activator of flowering. Belongs to the phosphatidylethanolamine-binding protein family.
