Protein
Serine/threonine-protein kinase BSK1
Organism
Arabidopsis thaliana
Function
Serine/threonine kinase that acts as positive regulator of brassinosteroid (BR) signaling downstream of the receptor kinase BRI1. Mediates signal transduction from BRI1 by functioning as substrate of BRI1 (PubMed:18653891). Functions as a positive regulator of plant immunity. May be involved in the regulation of pattern-triggered immunity (PTI) downstream of the flagellin receptor FLS2. Possesses kinase activity in vitro. Kinase activity is required for its function in innate immunity (PubMed:23532072).
Similarity
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
