CC -!- FUNCTION: Required for specifying floral primordia and establishing
CC early internode patterning events during inflorescence development.
CC {ECO:0000269|PubMed:15120075, ECO:0000269|PubMed:16741748}.
CC -!- SUBUNIT: May form heterodimeric complex with the TALE/KNOX proteins STM
CC and KNAT1/BP.
CC -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000305}.
CC -!- DOMAIN: The SR/KY and BELL domains are responsive for the interaction
CC between the TALE/BELL proteins and the TALE/KNOX proteins.
CC -!- SIMILARITY: Belongs to the TALE/BELL homeobox family. {ECO:0000305}.
