Source Description
UniProtAtypical and probable non DNA-binding bHLH transcription factor required for MONOPTEROS-dependent root initiation in embryo. Promotes the correct definition of the hypophysis cell division plane. Transcriptionally controlled by MONOPTEROS. Moves from its site of synthesis in pro-embryos cells into the hypophysis. Regulates brassinosteroid (BR) signaling by sequestering negative BR signaling components. May function as positive regulator of gibberellin signaling. May play a role in the regulation of light signaling and possibly auxin signaling. {ECO:0000269|PubMed:16527868, ECO:0000269|PubMed:20023194, ECO:0000269|PubMed:20220754, ECO:0000269|PubMed:22339648}.
