Function
PBL27 antibody targets a receptor-like cytoplasmic kinase. This kinase plays a crucial role in signal transduction between the host cell surface chitin receptor complex (CERK1-LYK5) and the intracellular MAPKKK5-dependent mitogen-activated protein kinase (MAPK) cascade. This cascade ultimately leads to chitin-induced immunity. Specifically, upon phosphorylation by CERK1 following chitin elicitation, PBL27 phosphorylates and activates MAPKKK5.
