General annotation (Comments)

Function	Plays a role in various cellular processes such as proliferation, differentiation and cell survival. The upstream activator of MAPK7 is the MAPK kinase MAP2K5. Upon activation, it translocates to the nucleus and phosphorylates various downstream targets including MEF2C. EGF activates MAPK7 through a Ras-independent and MAP2K5-dependent pathway. May have a role in muscle cell differentiation. May be important for endothelial function and maintenance of blood vessel integrity. MAP2K5 and MAPK7 interact specifically with one another and not with MEK1/ERK1 or MEK2/ERK2 pathways. Phosphorylates SGK1 at Ser-78 and this is required for growth factor-induced cell cycle progression By similarity. Involved in the regulation of p53/TP53 by disrupting the PML-MDM2 interaction By similarity. Ref.2
Catalytic activity	ATP + a protein = ADP + a phosphoprotein.
Cofactor	Magnesium By similarity.
Enzyme regulation	Activated by tyrosine and threonine phosphorylation. Activated in response to hyperosmolarity, hydrogen peroxide, and epidermal growth factor (EGF) By similarity.
Subunit structure	Interacts with MAP2K5. Forms oligomers By similarity. Interacts with MEF2A, MEF2C and MEF2D; the interaction phosphorylates the MEF2s and enhances transcriptional activity of MEF2A, MEF2C but not MEF2D. Interacts with SGK1 By similarity. Interacts with PML By similarity. Ref.2
Subcellular location	Cytoplasm. Nucleus. Nucleus › PML body By similarity. Note: Translocates to the nucleus upon activation By similarity.
Domain	The second proline-rich region may interact with actin targeting the kinase to a specific location in the cell. The TXY motif contains the threonine and tyrosine residues whose phosphorylation activates the MAP kinases.
Post-translational modification	Dually phosphorylated on Thr-219 and Tyr-221, which activates the enzyme By similarity.
Sequence similarities	Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily. Contains 1 protein kinase domain.
