NCBI Protein Information
activation-tagged BRI1(brassinosteroid-insensitive 1)-suppressor 1
NCBI Summary
Encodes a basic helix#Aeiloop#Aeihelix transcription factor that acts downstream of MP in root initiation. TMO7 protein moves to the hypophysis and to vascular cells, contributing to MP-dependent root formation. Promotes the correct definition of the hypophysis cell division plane.

UniProt Comments
Atypical 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.
