comment
  • FUNCTION May play a role in signal transduction of hyperosmotic response (Probable). Together with PYL10, PP2C53 and SAPK10, may form an abscisic acid (ABA) signaling module involved in stress response (PubMed:26491145).CATALYTIC ACTIVITY L-seryl-[protein] + ATP = O-phospho-L-seryl-[protein] + ADP + H(+)CATALYTIC ACTIVITY L-threonyl-[protein] + ATP = O-phospho-L-threonyl-[protein] + ADP + H(+)ACTIVITY REGULATION Activated by hyperosmotic stress and abscisic acid (ABA).SUBUNIT Interacts with PP2C53.SUBCELLULAR LOCATION Expressed in leaf blades, leaf sheaths and roots. Expressed in shoots and roots of young seedlings.INDUCTION Neither induced by hyperosmotic stress nor by ABA.DOMAIN The C-terminal region is necessary for the kinase activation in response to ABA treatment.PTM May be phosphorylated.SIMILARITY Belongs to the protein kinase superfamily. Ser/Thr protein kinase family.
