Functional Description ? help Back to Top
Source Description
UniProtAtypical bHLH transcription factor that acts as positive regulator of cell elongation downstream of multiple external and endogenous signals by direct binding to the promoters and activation of the two expansin genes EXPA1 and EXPA8, encoding cell wall loosening enzymes. Transcriptional activity is inhibited when binding to the bHLH transcription factor IBH1. {ECO:0000269|PubMed:23221598}.
