    basic FUNCTION
  • serine/threonine kinase, may be playing a role in the early onset of apoptosis
  • involved in hypertrophic differentiation of chondrocytes
  • involved in cardiomyocyte proliferation and angiogenesis during development
  • involved in Sp1 phosphorylation
  • mediates IL1A-induced down-regulation of aggrecan gene expression in chondrocytes
  • may be regulating the early secretory pathway
  • substrates of this kinase include ATF2, MEF2C, MAX, CDC25B, p53, suggesting a role in stress related transcription and cell cycle regulation
  • controls myogenesis by antagonizing the activation of the JNK proliferation-promoting pathway, before its direct effect on muscle differentiation-specific gene transcription (fundamental role in muscle formation)
  • recruited to muscle-specific gene promoters during muscle development suggesting that indeed MAPK14 might play an important role at the chromatin
  • role in activating CREB1 metabolic pathway in the events leading to erythroid differentiation)
  • its activity promotes timely checkpoint satisfaction by indirectly influencing the motor proteins (e.g., Klp10, Klp67A) involved in regulating the dynamics of kinetochore microtubule ends
  • in intestinal epithelial cells contributes to the host immune responses against enteric bacteria by the recruitment of immune cells
  • MAPK14 recruitment to target genes appears to be a broad mechanism to regulate transcription
  • its activity is not just necessary for gene promoter activation but might also be necessary for the nascent mRNA elongation of MAPK14-dependent genes
  • regulates expression of osteoblast-specific genes by phosphorylation of osterix (SP7)
  • maintains CDH1 expression by suppressing MAP3K7-NFKB signaling, thus impeding the induction of EMT in human primary mesothelial cells
  • plays an important role in the regulation of hematopoietic stem cellself-renewal in vitro and inhibition of MAPK14 activation with a small molecule inhibitor may represent a novel approach to promote ex vivo expansion of hematopoietic stem cell
  • controls prothrombin expression by regulated RNA 3prime end processing
  • regulates G1-S transition in hypoxic cardiac fibroblasts
  • MAPK14-signaling is a central pathway for the integration of instructive signals in dendritic cells for T(H)17 differentiation and inflammation

    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • regulate TEAD1 and CEBPB transcriptional activity in the absence of environmental stress and suggests a role for MAPK14 in the expression of extracellular matrix components that maintain organ architecture
  • SP7 (Osterix) is a novel substrate for MAPK14, and Ser-73 and Ser-77 are the regulatory sites phosphorylated by MAPK14
  • MAPKAPK2 and MAPK14 function in concert to phosphorylate Keratin 8, Keratin 18, and Keratin 20 in intestinal epithelia
  • interacting with MYCBP2 (modulates TRPV1 desensitization through MAPK14 signaling which presents not only a novel model for the modulation of TRPV1-mediated signals but also expands the role of MAPK14 in the regulation of activity-induced receptor internalization)
  • interaction between phosphorylated MAPK14 and cleaved N-terminal ATF6 could results in a protective effect against the vicious cycle of oxidative stress-ER stress by induction of ER chaperones and ERAD components

  • PDGFB-induced activation of MAPK14 was significantly suppressed by SERPINA12
