Binding to pectin may have significance in the control of cell expansion, morphogenesis and development. Required during plant's response to pathogen infection and in plant defense against heavy metal toxicity. Phosphorylates the oxygen-evolving enhancer protein 2 (OEE2) in an GRP-3-dependent manner.CATALYTIC ACTIVITY:ATP a protein = ADP a phosphoprotein.SUBUNIT:Interacts with the glycine-rich protein GRP-3 and the type 2C protein phosphatase KAPP. Component of a 500 kDa complex, composed of WAK1, GRP3 and KAPP. Interacts with the oxygen- evolving enhancer protein 2 (OEE2).TISSUE SPECIFICITY:Predominantly expressed in green tissues such as stems and leaves. Detected at organ junctions.DEVELOPMENTAL STAGE:Expressed in shoot and root apical meristems, and in expanding leaves and sepals.INDUCTION:Induced by salicylic acid (SA) or INA, methyl jasmonate, ethylene, wounding and pathogen infection. Accumulated in roots after Aluminum exposure.MISCELLANEOUS:Binding to polygalacturonic acid (PGA) multimers is calcium-dependent.SIMILARITY:Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.SIMILARITY:Contains 2 EGF-like domains.SIMILARITY:Contains 1 protein kinase domain.SEQUENCE CAUTION:Sequence=AAA32844.1; Type=Frameshift; Positions=65, 117; Sequence=AAF81356.1; Type=Erroneous gene model prediction; "
