Regulates, in response to brassinosteroid binding, 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. Binds brassinolide, and less effectively castasterone, but not 2,3,22,23-O-tetramethylbrassinolide or ecdysone. May be involved in a feedback regulation of brassinosteroid biosynthesis. Phosphorylates BRI1-associated receptor kinase 1 (BAK1), Transthyretin-Like protein (TTL) and SERK1 on 'Ser-299' and 'Thr-462' in vitro. May have a guanylyl cyclase activity.<ref>PMID:10557222</ref> <ref>PMID:10938344</ref> <ref>PMID:17138891</ref> <ref>PMID:17520012</ref> <ref>PMID:18694562</ref> <ref>PMID:19124768</ref> [[http://www.uniprot.org/uniprot/BAK1_ARATH BAK1_ARATH]] Dual specificity kinase acting on both serine/threonine- and tyrosine-containing substrates.
