CC   -!- COFACTOR:
CC       Name=Mg(2+); Xref=ChEBI:CHEBI:18420; Evidence={ECO:0000250};
CC   -!- ACTIVITY REGULATION: Activated by tyrosine and threonine
CC       phosphorylation. {ECO:0000250}.
CC   -!- TISSUE SPECIFICITY: Leaves, roots, root apices, and dormant and growing
CC       axillary buds.
CC   -!- DOMAIN: The TXY motif contains the threonine and tyrosine residues
CC       whose phosphorylation activates the MAP kinases.
CC   -!- PTM: Dually phosphorylated on Thr-220 and Tyr-222, which activates the
CC       enzyme. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the protein kinase superfamily. CMGC Ser/Thr
CC       protein kinase family. MAP kinase subfamily. {ECO:0000305}.
CC   -!- CAUTION: It is uncertain whether Met-1, Met-14 or Met-30 is the
CC       initiator. {ECO:0000305}.
