MPK4a

Gene
MPK4a
Protein
Mitogen-activated protein kinase 4a
Organism
Physcomitrella patens subsp. patens
Length
375 amino acids
Function
The CERK1, MEKK1a/b, MKK1a/b/c and MPK4a/b proteins are involved in pathogen defense. The pathway induces rapid growth inhibition, cell wall depositions and accumulation of defense-related transcripts. This protein is required for innate immunity triggered by pathogen-associated molecular patterns (PAMPs). Involved in resistance to necrotrophic fungi B.cinerea and A.brassicicola. Involved in the transduction of signals from chitosan perception to the activation of defense genes.
Similarity
Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.
