WAG1

Gene
WAG1
Protein
Serine/threonine-protein kinase WAG1
Organism
Arabidopsis thaliana
Length
476 amino acids
Function
Serine/threonine-protein kinase involved in the regulation of auxin signaling. Acts as a positive regulator of cellular auxin efflux and regulates organ development by enhancing PIN-mediated polar auxin transport. Phosphorylates conserved serine residues in the PIN auxin efflux carriers. Phosphorylation of PIN proteins is required and sufficient for apical-basal PIN polarity that enables directional intercellular auxin fluxes, which mediate differential growth, tissue patterning and organogenesis. Acts as suppressors of root waving.
Similarity
Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
