Sequence status	Complete.
Sequence processing	The displayed sequence is further processed into a mature form.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	Involved in both the initiation and regulation of meiosis, mitosis, and postmitotic functions in differentiated cells by phosphorylating a number of transcription factors such as ELK1. Phosphorylates EIF4EBP1; required for initiation of translation. Phosphorylates microtubule-associated protein 2 (MAP2). Phosphorylates SPZ1 By similarity. Phosphorylates heat shock factor protein 4 (HSF4) and ARHGEF2.
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Cofactor	Magnesium By similarity.
Enzyme regulation	Activated by phosphorylation on tyrosine and threonine in response to insulin and NGF. Both phosphorylations are required for activity By similarity.
Subunit structure	Interacts with MORG1 By similarity. Binds to HIV-1 Nef through its SH3 domain. This interaction inhibits its tyrosine-kinase activity. Interacts with its substrates HSF4 and ARHGEF2. Interacts with NISCH.
Domain	The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
Post-translational modification	Dually phosphorylated on Thr-185 and Tyr-187, which activates the enzyme. Ref.7 Ref.9 Ref.10 Ref.11 Ref.12 Ref.14 Ref.15 Ref.16
Sequence similarities	Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily. Contains 1 protein kinase domain.
