May play a role in meristem function, and may be involved in maintaining cells in an undifferentiated, meristematic state. Probably binds to the DNA sequence 5'-TGAC-3'. May form heterodimeric complex with the TALE/BELL protein BEL1, BLH1 and BLH2. Interacts with OFP12 and OFP14. Interacts with BZIP30 (PubMed:27402171). Expressed predominantly in shoot apices of seedlings, in the receptacle and developing pistil of flowers and in axillary buds of inflorescence stems. Belongs to the TALE/KNOX homeobox family.
