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. Ref.7 Ref.8 Ref.9

Catalytic activity

ATP + a protein = ADP + a phosphoprotein.

Cofactor

Magnesium By similarity.

Enzyme regulation

Activated by tyrosine and threonine phosphorylation By similarity. Activated in response to hyperosmolarity, hydrogen peroxide, and epidermal growth factor (EGF).

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 By similarity.

Subcellular location

Cytoplasm. Nucleus. Note: Translocates to the nucleus upon activation. Ref.7

Tissue specificity

Expressed in many adult tissues. Abundant in heart, placenta, lung, kidney and skeletal muscle. Not detectable in liver. Ref.2

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. Autophosphorylated in vitro on threonine and tyrosine residues when the C-terminal part of the kinase, which could have a regulatory role, is absent.

Sequence similarities

Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. MAP kinase subfamily.

Contains 1 protein kinase domain.

Sequence caution

The sequence AAA81381.1 differs from that shown. Reason: Frameshift at positions 19 and 32.

Isoform 2 (identifier: Q13164-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-139: Missing.
Note: No experimental confirmation available.
Isoform 3 (identifier: Q13164-3)

The sequence of this isoform differs from the canonical sequence as follows:
     493-816: DGPSAPLEAP...LADLPDLQDP → GALWAGRVGR...KWPQRTPGGS
Isoform 4 (identifier: Q13164-4)

The sequence of this isoform differs from the canonical sequence as follows:
