CC -!- FUNCTION: Atypical and probable non DNA-binding bHLH transcription
CC factor that acts as negative regulator of cell elongation and plant
CC development. Binds the transcription factor ILI1 and forms a
CC heterodimer of antagonistic bHLH transcription factors that function
CC downstream of BZR1 to mediate brassinosteroid regulation of cell
CC elongation and lamina inclination (By similarity). {ECO:0000250}.
CC -!- SUBUNIT: Interacts with ILI1. {ECO:0000250}.
CC -!- SIMILARITY: Belongs to the bHLH protein family.
CC -!- SEQUENCE CAUTION:
CC Sequence=EEC78174.1; Type=Erroneous initiation; Note=Truncated N-terminus.; Evidence={ECO:0000305};
