High impact information on MAP3K2

 

Biological context of MAP3K2

 

Associations of MAP3K2 with chemical compounds

 

Regulatory relationships of MAP3K2

  • Furthermore, MEKK2 immunoprecipitates activated c-Jun in an IL-1 dependent manner and this activity was inhibited by the selective JNK inhibitor SP600125 [6].
 

Other interactions of MAP3K2

  • No scaffold protein was required for the MEKK2-JNKK2-JNK1 tripartite-complex formation [7].
  • Moreover, both MEKK2 and MEKK3 coimmunoprecipitated with endogenous WNK1 from cell lysates [8].
  • WNK1 activates ERK5 by an MEKK2/3-dependent mechanism [8].
  • The biological roles of MEKK2, 3 and 4 are under investigation and undoubtedly homologous deletion of these MEKK family members will be invaluable at determining the biological functions of these MEKKs [9].
  • In contrast, MEKK2 and PKA also increased shedding of TNF receptor 2, suggesting that these kinases contribute to a general program regulating ectodomain shedding [10].
