Protein
Serine/threonine-protein kinase PBS1
Organism
Arabidopsis thaliana
Function
Protein kinase required for plant defense mechanism mediated by the disease resistance (R) protein RPS5. In case of infection by Pseudomonas syringae, AvrPphB triggers RPS5-mediated defense mechanism via the cleavage of PBS1. Both kinase activity and cleavage by avrPphB are independently required to trigger the RPS5-mediated resistance. Contributes to PAMP-triggered immunity (PTI) signaling and defense responses downstream of FLS2.
Similarity
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
