Functioni

Tumor suppressor serine/threonine-protein kinase involved in mTORC1 signaling and post-transcriptional regulation. Phosphorylates FOXO3, ERK3/MAPK6, ERK4/MAPK4, HSP27/HSPB1, p53/TP53 and RHEB. Acts as a tumor suppressor by mediating Ras-induced senescence and phosphorylating p53/TP53. Involved in post-transcriptional regulation of MYC by mediating phosphorylation of FOXO3: phosphorylation of FOXO3 leads to promote nuclear localization of FOXO3, enabling expression of miR-34b and miR-34c, 2 post-transcriptional regulators of MYC that bind to the 3'UTR of MYC transcript and prevent MYC translation. Acts as a negative regulator of mTORC1 signaling by mediating phosphorylation and inhibition of RHEB. Part of the atypical MAPK signaling via its interaction with ERK3/MAPK6 or ERK4/MAPK4: the precise role of the complex formed with ERK3/MAPK6 or ERK4/MAPK4 is still unclear, but the complex follows a complex set of phosphorylation events: upon interaction with atypical MAPK (ERK3/MAPK6 or ERK4/MAPK4), ERK3/MAPK6 (or ERK4/MAPK4) is phosphorylated and then mediates phosphorylation and activation of MAPKAPK5, which in turn phosphorylates ERK3/MAPK6 (or ERK4/MAPK4). Mediates phosphorylation of HSP27/HSPB1 in response to PKA/PRKACA stimulation, inducing F-actin rearrangement.6 Publications

Caution

The role of p38 MAPK kinases is unclear in phosphorylation and activation of Mapkapk5. According to some reports, it interacts and is phosphorylated by p38-alpha/MAPK14 and p38-beta/MAPK11 (PubMed:9480836). According to other reports, it is not activated by p38-alpha/MAPK14 and p38-beta/MAPK11 (PubMed:14560018). An explanation for these discrepancies, might be that the interaction with p38 MAPK kinases is weak and occurs only under specific conditions.2 Publications

Catalytic activityi

ATP + a protein = ADP + a phosphoprotein.1 Publication

Activity regulationi

Activated following phosphorylation at Thr-182 by p38-alpha/MAPK14, p38-beta/MAPK11, ERK2/MAPK1, ERK3/MAPK6, and ERK4/MAPK4. Activated by stress-related extracellular stimuli; such as H2O2, arsenite, anisomycin TNF alpha and also PMA and the calcium ionophore A23187; but to a lesser extent. In vitro, activated by SQSTM1. Inhibited by diterpenoid alkaloid noroxoaconitine.2 Publications

Disruption phenotypei

Phenotypes are different depending on reports. According to a first report, mice are viable and fertile and do not show changes in tissue morphology and behavior: they exhibit the same susceptibility to LPS-induced endotoxic shock as wild-type animals and do not show the defects in LPS-induced biosynthesis of inflammatory cytokines known to occur with Mapkapk2-deficient animals (PubMed:14560018). According to another report, both homozygous and heterozygous mutant mice are highly susceptible to skin carcinogenesis induced by DMBA (PubMed:17254968). According to a third report, mutant show embryonic lethality around E11 in a C57BL/6 background (PubMed:15538386).3 Publications

In addition, they also explore further into the open arm on the elevated plus maze and are less active in the closed arm compared to littermate controls. Male knockin mice display no differences in anxiety, but their locomotor activity increases compared to non-transgenic littermates. 1 Publication1

Phosphorylated on Thr-182 ERK3/MAPK6 or ERK4/MAPK4; which is the regulatory phosphorylation site and is located on the T-loop/loop 12, leading to activation. Phosphorylation at Thr-182 by p38-alpha/MAPK14, p38-beta/MAPK11 is subject to debate. Phosphorylated at Ser-115 by PKA/PRKACA, leading to localization to the cytoplasm. Autophosphorylated.4 Publications
