CC   -!- FUNCTION: Atypical and probable non DNA-binding bHLH transcription
CC       factor that acts as a positive regulator of grain size. Binds the
CC       transcription repressor APG and forms a heterodimer of antagonistic
CC       basic helix-loop-helix transcription factors that regulates grain
CC       length and weight by controlling cell elongation in lemma and palea (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Interacts with APG. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Nucleus {ECO:0000255|PROSITE-ProRule:PRU00981}.
CC   -!- SIMILARITY: Belongs to the bHLH protein family.
