General annotation (Comments)

Function	Required downstream of Raf in the sevenless (sev), torso (tor), and Drosophila EGF receptor homolog (DER) signal transduction pathways. Ref.7
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Cofactor	Magnesium By similarity.
Enzyme regulation	Activated by tyrosine and threonine phosphorylation By similarity.
Subcellular location	Cytoplasm. Nucleus Ref.1.
Tissue specificity	In third instar larvae, expressed in eye imaginal disks. In adults, expressed in head and body.
Developmental stage	Embryos, larvae and adults. Ref.1
Domain	The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
Post-translational modification	Dually phosphorylated on Thr-248 and Tyr-250, which activates the enzyme By similarity. Phosphorylated on tyrosine residue(s) in response to insulin. Ref.1
Sequence similarities	Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily. Contains 1 protein kinase domain.
