MAPK8
MAPK8 (Mitogen-activated protein kinase 8) is a protein kinase, an enzyme that switches other proteins on by adding phosphate groups. The public catalogues list it as a drug target, and clinical evidence ties its variants to diagnosis, prognosis or drug response.
Overview
Serine/threonine-protein kinase involved in various processes such as cell proliferation, differentiation, migration, transformation and programmed cell death. Extracellular stimuli such as pro-inflammatory cytokines or physical stress stimulate the stress-activated protein kinase/c-Jun N-terminal kinase (SAP/JNK) signalling pathway. In this cascade, two dual specificity kinases MAP2K4/MKK4 and MAP2K7/MKK7 phosphorylate and activate MAPK8/JNK1.
Open Targets scores its association with cancer at 0.58 (direct and indirect evidence; datatypes clinical 0.06, affected pathway 0.89, literature 0.99, genetic association 0.00, animal model 0.51).

- 1 · What it is
MAPK8 (Mitogen-activated protein kinase 8) is a protein kinase, an enzyme that switches other proteins on by adding phosphate groups. The public catalogues list it as a drug target, and clinical evidence ties its variants to diagnosis, prognosis or drug response.
- 2 · What goes wrong in cancer
Serine/threonine-protein kinase involved in various processes such as cell proliferation, differentiation, migration, transformation and programmed cell death.
- 3 · How drugs use it
No product in this corpus aims at MAPK8 yet. Kinases are switched on by binding ATP inside the cell, so most drugs are small molecules shaped to plug that ATP pocket.

Biology
Serine/threonine-protein kinase involved in various processes such as cell proliferation, differentiation, migration, transformation and programmed cell death. Extracellular stimuli such as pro-inflammatory cytokines or physical stress stimulate the stress-activated protein kinase/c-Jun N-terminal kinase (SAP/JNK) signalling pathway. In this cascade, two dual specificity kinases MAP2K4/MKK4 and MAP2K7/MKK7 phosphorylate and activate MAPK8/JNK1. In turn, MAPK8/JNK1 phosphorylates a number of transcription factors, primarily components of AP-1 such as JUN, JDP2 and ATF2 and thus regulates AP-1 transcriptional activity. Phosphorylates the replication licensing factor CDT1, inhibiting the interaction between CDT1 and the histone H4 acetylase HBO1 to replication origins. Loss of this interaction abrogates the acetylation required for replication initiation. Location: Cytoplasm; Nucleus; Synapse (UniProt). Locus 10q11.22 (HGNC).
