MAP kinase-activated protein kinase 3 (MAPKAPK3)

Target (abbrv.) MAPKAPK3
Target (full name) MAP kinase-activated protein kinase 3
Somalogic ID (Sequence ID) SL004765 (3822-54_2)
Entrez Gene Symbol MAPKAPK3
UniProt ID Q16644
UniProt Comment
  • Stress-activated serine/threonine-protein kinase involved in cytokines production, endocytosis, cell migration, chromatin remodeling and transcriptional regulation. Following stress, it is phosphorylated and activated by MAP kinase p38-alpha/MAPK14, leading to phosphorylation of substrates. Phosphorylates serine in the peptide sequence, Hyd-X-R-X(2)-S, where Hyd is a large hydrophobic residue. MAPKAPK2 and MAPKAPK3, share the same function and substrate specificity, but MAPKAPK3 kinase activity and level in protein expression are lower compared to MAPKAPK2. Phosphorylates HSP27/HSPB1, KRT18, KRT20, RCSD1, RPS6KA3, TAB3 and TTP/ZFP36. Mediates phosphorylation of HSP27/HSPB1 in response to stress, leading to dissociate HSP27/HSPB1 from large small heat-shock protein (sHsps) oligomers and impair their chaperone activities and ability to protect against oxidative stress effectively. Involved in inflammatory response by regulating tumor necrosis factor (TNF) and IL6 production post-transcriptionally: acts by phosphorylating AU-rich elements (AREs)-binding proteins, such as TTP/ZFP36, leading to regulate the stability and translation of TNF and IL6 mRNAs. Phosphorylation of TTP/ZFP36, a major post-transcriptional regulator of TNF, promotes its binding to 14-3-3 proteins and reduces its ARE mRNA affinity leading to inhibition of dependent degradation of ARE-containing transcript. Involved in toll-like receptor signaling pathway (TLR) in dendritic cells: required for acute TLR-induced macropinocytosis by phosphorylating and activating RPS6KA3. Also acts as a modulator of Polycomb-mediated repression.

Entrez Gene Symbol MIF
UniProt ID P14174
UniProt Comment
  • Pro-inflammatory cytokine. Involved in the innate immune response to bacterial pathogens. The expression of MIF at sites of inflammation suggests a role as mediator in regulating the function of macrophages in host defense. Counteracts the anti-inflammatory activity of glucocorticoids. Has phenylpyruvate tautomerase and dopachrome tautomerase activity (in vitro), but the physiological substrate is not known. It is not clear whether the tautomerase activity has any physiological relevance, and whether it is important for cytokine activity.

Strong trans-pQTL with MAPKAPK3 may be used to identify link to cis-encoded genes.

This locus harbours a replicated trans-pQTL to MAP kinase-activated protein kinase 3 (MAPKAPK3). A second trans-pQTL Macrophage migration inhibitory factor (MIF) did not have sufficient replication power in QMDiab, but was still nominally significant (p=1.2×10-3).

The information gathered here is a result of an attempt to keep track of all interesting information that we encountered while investigating these loci. Please bear in mind that the annotation given here is neither complete nor free of errors, and that all information provided here should be confirmed by additional literature research before being used as a basis for firm conclusions or further experiments.
