Target Data

Function Dual specificity protein kinase which acts as an essential component of the MAP kinase signal transduction pathway. Binding of extracellular ligands such as growth factors, cytokines and hormones to their cell-surface receptors activates RAS and this initiates RAF1 activation. RAF1 then further activates the dual-specificity protein kinases MAP2K1/MEK1 and MAP2K2/MEK2. Both MAP2K1/MEK1 and MAP2K2/MEK2 function specifically in the MAPK/ERK cascade, and catalyze the concomitant phosphorylation of a threonine and a tyrosine residue in a Thr-Glu-Tyr sequence located in the extracellular signal-regulated kinases MAPK3/ERK1 and MAPK1/ERK2, leading to their activation and further transduction of the signal within the MAPK/ERK cascade. Depending on the cellular context, this pathway mediates diverse biological functions such as cell growth, adhesion, survival and differentiation, predominantly through the regulation of transcription, metabolism and cytoskeletal rearrangements. One target of the MAPK/ERK cascade is peroxisome proliferator-activated receptor gamma (PPARG), a nuclear receptor that promotes differentiation and apoptosis. MAP2K1/MEK1 has been shown to export PPARG from the nucleus. The MAPK/ERK cascade is also involved in the regulation of endosomal dynamics, including lysosome processing and endosome cycling through the perinuclear recycling compartment (PNRC), as well as in the fragmentation of the Golgi apparatus during mitosis.

  1. Upregulation of miR101 inhibited DLBCL cell proliferation and facilitated apoptosis by inhibiting the expression of MEK1. PMID: 30365139
  2. Somatic activating mutations in MAP2K1 cause melorheostosis. PMID: 29643386
  3. Here the authors identified a direct interaction of both MEK1 and MEK2 with AKT. The interaction between MEK and AKT affects cell migration and adhesion, but not proliferation.

  16. mutations in MAP2K1, which are frequently associated with neurological complications and intellectual disability, can be associated with a milder clinical and neurocognitive profile more typical of individuals with Noonan syndrome. Variability of expression may arise from a complex interplay between RAS/MAPK pathway genotype, epigenetics, medical and obstetric factors, and environmental influences. PMID: 27862862

  19. MEK1 is constitutively and mainly phosphorylated at the Thr-292, Ser-298, Thr-386, and Thr-388 residues in vivo, and combinations of phosphorylations at these four residues produce at least six phosphorylated variants of MEK1. The phosphorylation statuses of Thr-292, Ser-298, Thr-386, and Thr-388 residues vary widely during activation and deactivation of the MAPK pathway. PMID: 27169363
  20. TNFRSF14 and MAP2K1 mutations are the most frequent genetic alterations found in pediatric-type follicular lymphoma (PTFL) and occur independently in most cases, suggesting that both mutations might play an important role in PTFL lymphomagenesis. PMID: 28533310
  21. There was no statistically significant association between BRAF or MAP2K1 mutation and anatomic site, unifocal versus multifocal presentation, or clinical outcome in Langerhans cell histiocytosis. PMID: 26980021
