1.A.87.2.6
Protein BRASSINOSTEROID INSENSITIVE 1, BRI1, of 1196 aas and 2 or 3 TMSs. Receptor with kinase activity acting on both serine/threonine- and tyrosine-containing substrates. In response to brassinosteroid binding, it regulates a signaling cascade involved in plant development, including expression of light- and stress-regulated genes, promotion of cell elongation, normal leaf and chloroplast senescence, and flowering. It binds brassinolide, and less effectively, castasterone (Oh et al. 2009).
