Protein: Probable serine/threonine-protein kinase BSK3 (EC 2.7.11.1) (Brassinosteroid-signaling kinase 3) (OsBSK3) (Receptor-like cytoplasmic kinase 173) (OsRLCK173) (B9FDE0)
Organism: Oryza sativa subsp. japonica (Rice)
Function: Probable serine/threonine kinase that acts as positive regulator of brassinosteroid (BR) signaling downstream of BRI1.
Subcellular location: Cell membrane {ECO:0000269|PubMed:26697897}; Lipid-anchor {ECO:0000305|PubMed:26697897}. Note=Plasma membrane localization is required for its function in the regulation of brassinosteroid signaling. {ECO:0000269|PubMed:26697897}.
