CC   -!- FUNCTION: Serine/threonine kinase which acts as an essential
CC       component of the MAP kinase signal transduction pathway. MAPK12 is
CC       one of the four p38 MAPKs which play an important role in the
CC       cascades of cellular responses evoked by extracellular stimuli
CC       such as proinflammatory cytokines or physical stress leading to
CC       direct activation of transcription factors such as ELK1 and ATF2.
CC       Accordingly, p38 MAPKs phosphorylate a broad range of proteins and
CC       it has been estimated that they may have approximately 200 to 300
CC       substrates each. Some of the targets are downstream kinases such
CC       as MAPKAPK2, which are activated through phosphorylation and
CC       further phosphorylate additional targets. Plays a role in myoblast
CC       differentiation and also in the down-regulation of cyclin D1 in
CC       response to hypoxia in adrenal cells suggesting MAPK12 may inhibit
CC       cell proliferation while promoting differentiation. Phosphorylates
CC       DLG1. Following osmotic shock, MAPK12 in the cell nucleus
CC       increases its association with nuclear DLG1, thereby causing
CC       dissociation of DLG1-SFPQ complexes. This function is independent
CC       of its catalytic activity and could affect mRNA processing and/or
CC       gene transcription to aid cell adaptation to osmolarity changes in
CC       the environment. Regulates UV-induced checkpoint signaling and
CC       repair of UV-induced DNA damage and G2 arrest after gamma-
CC       radiation exposure. MAPK12 is involved in the regulation of SLC2A1
CC       expression and basal glucose uptake in L6 myotubes; and negatively
CC       regulates SLC2A4 expression and contraction-mediated glucose
CC       uptake in adult skeletal muscle. C-Jun (JUN) phosphorylation is
CC       stimulated by MAPK14 and inhibited by MAPK12, leading to a
CC       distinct AP-1 regulation. MAPK12 is required for the normal
CC       kinetochore localization of PLK1, prevents chromosomal instability
CC       and supports mitotic cell viability. MAPK12-signaling is also
CC       positively regulating the expansion of transient amplifying
CC       myogenic precursor cells during muscle growth and regeneration.

CC       activation. {ECO:0000269|PubMed:17724032}.
CC   -!- DOMAIN: The TXY motif contains the threonine and tyrosine residues
CC       whose phosphorylation activates the MAP kinases.
CC   -!- PTM: Dually phosphorylated on Thr-183 and Tyr-185 by MAP2K3/MKK3
CC       and MAP2K6/MKK6, which activates the enzyme.
CC       {ECO:0000269|PubMed:11010976, ECO:0000269|PubMed:17724032}.
CC   -!- PTM: Ubiquitinated. Ubiquitination leads to degradation by the
CC       proteasome pathway. {ECO:0000269|PubMed:17724032}.
CC   -!- DISEASE: Note=MAPK is overexpressed in highly metastatic breast
CC       cancer cell lines and its expression is preferentially associated
CC       with basal-like and metastatic phenotypes of breast tumor samples.
CC   -!- SIMILARITY: Belongs to the protein kinase superfamily. CMGC
CC       Ser/Thr protein kinase family. MAP kinase subfamily.
CC       {ECO:0000305}.
CC   -!- SIMILARITY: Contains 1 protein kinase domain.
