comment
  • 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.SUBUNIT Interacts with ILI1 (PubMed:20009022). Binds to ILI5/BUL1 and BC1 (PubMed:27879391). Interacts with BCL1 and BCL2 (PubMed:34360554).TISSUE SPECIFICITY Highly expressed in roots and at lower levels in leaf blades, leaf sheaths, lamina joint, stems and panicles.INDUCTION Repressed by epibrassinolide.MISCELLANEOUS Plants over-expressing IBH1 show erect leaves with reduced angles of inclination.SIMILARITY Belongs to the bHLH protein family.
