Disease relevance of Map2k1

 

High impact information on Map2k1

  • Conditional expression of a dominant-negative form of MEK1 in the postnatal murine forebrain inhibited ERK activation and caused selective deficits in hippocampal memory retention and the translation-dependent, transcription-independent phase of hippocampal L-LTP [5].
  • The transforming-growth-factor-beta-activated kinase TAK1 is a member of the mitogen-activated protein kinase kinase kinase family, which couples extracellular stimuli to gene transcription [6].
  • These data indicate that MEK inhibitors represent a promising, noncytotoxic approach to the clinical management of colon cancer [7].
  • Activation of stress-activated protein kinase by MEKK1 phosphorylation of its activator SEK1 [8].
  • Here we report that MAPK-K as well as Erk1 and 2 are constitutively active in v-raf-transformed cells [9].

Enzymatic interactions of Map2k1

  • MEK-1 is a dual threonine and tyrosine recognition kinase that phosphorylates and activates mitogen-activated protein kinase (MAPK) [26].
  • Furthermore, the MEK-phosphorylating activity of protein kinase Czeta (PKCzeta) was also enhanced after TPO stimulation of T69Mpl, contributing to ERK activity [27].
  • The Mek1 dual specificity protein kinase phosphorylates and activates the mitogen-activated protein kinases Erk1 and Erk2 in response to mitogenic stimulation [28].

Analytical, diagnostic and therapeutic context of Map2k1

  • MEK1 transgenic mice showed a dramatic increase in cardiac function, as measured by echocardiography and isolated working heart preparation, without signs of decompensation over time [1].
  • Laser scanning cytometry and flow cytometry were used to determine: (1) whether expression of phosphorylated ERKs was cell cycle-related; and (2) whether cell-cycle alterations by agents could be modified after addition of the mitogen-activated protein kinase/ERK kinase (MEK) 1 inhibitor PD98059 [38].
  • Immunoprecipitation experiments have shown that the time courses of activation and deactivation of both isoforms of MAPKK were superimposed [39].
  • Western blots analysis was performed to determine the levels of proteins involved in the MEK-MAPK and apoptotic pathways [40].
  • Studying the protein expression profile of seven HCC xenografts revealed that their growth rate was positively correlated with the levels of phosphorylated MEK [41].
