Differential contribution of Arabidopsis chitin receptor complex components to defense signaling and ubiquitination-dependent endocytotic removal from the plasma membrane.

Abstract excerpt

In Arabidopsis, the enzymatically active lysin motif-containing receptor-like kinase (LysM-RLK) CHITIN ELICITOR RECEPTOR KINASE 1 (CERK1) and the pseudokinases LYSIN MOTIF-CONTAINING RECEPTOR-LIKE KINASE 5 (LYK5) and LYK4 are the core components of the canonical chitin receptor complex. CERK1 dimerizes and autophosphorylates upon chitin binding, resulting in activation of chitin signaling. In this study, we...
