Q01I07 · IBH1_ORYSI

Function

function

Atypical and probable non DNA-binding bHLH transcription factor that acts as a negative regulator of cell elongation and plant development. Binds the transcription factor ILI1 and forms a heterodimer of antagonistic bHLH transcription factors that function downstream of BZR1 to mediate brassinosteroid regulation of cell elongation and lamina inclination (By similarity).
