Function
Acts as a regulator of cell proliferation and elongation in the root and shoot (PubMed:25049386, PubMed:28652362). Regulates roots architecture and primary root protophloem differentiation (PubMed:25049386, PubMed:28652362). Probable transcription regulator. Regulated by the auxin response factor ARF5. Polarly localized in vascular cells and subject to endocytic recycling. Required for CPD expression and for correct nuclear auxin response. Mediates cross-talk between the auxin and brassinosteroid pathways. BRX is a target for auxin-induced, proteasome-mediated degradation.
