Phosphorylation of Xenopus mitogen-activated protein (MAP) kinase kinase by MAP kinase kinase kinase and MAP kinase.

Journal of Biological Chemistry, 1993
Xenopus 45-kDa mitogen-activated protein (MAP) kinase kinase (MAPKK) is a serine/threonine/tyrosine kinase, which activates MAP kinase (MAPK) by phosphorylating its threonine and tyrosine residues. MAPKK is active only when its threonine and/or serine residues are phosphorylated.

Benzimidazoisoquinoline derivatives inhibit glioblastoma cell proliferation through down-regulating Raf/MEK/ERK and PI3K/AKT pathways

Cancer Cell International, 2018
Background Recent studies showed that benzimidazoleisoquinolinone derivatives exhibit anticancer activity against human cancer cell lines. The aim of this study is to evaluate the anti-tumor effects and mechanisms of benzimidazoleisoquinolinones in ...

Identification and Characterization of a Novel MAP Kinase Kinase Kinase, MLTK [PDF]

Journal of Biological Chemistry, 2001
The MAPK cascades regulate a wide variety of cellular functions, including cell proliferation, differentiation, and stress responses. Here we have identified a novel MAP kinase kinase kinase (MAPKKK), termed MLTK (for MLK-like mitogen-activated protein triple kinase), whose expression is increased by activation of the ERK/MAPK pathway.

The deleted in brachydactyly B domain of ROR2 is required for receptor activation by recruitment of Src [PDF]

, 2007
The transmembrane receptor 'ROR2' resembles members of the receptor tyrosine kinase family of signalling receptors in sequence but its' signal transduction mechanisms remain enigmatic.

Identification of a Novel Inhibitor of Mitogen-activated Protein Kinase Kinase*

Journal of Biological Chemistry, 1998
The compound U0126 (1,4-diamino-2,3-dicyano-1,4-bis[2-aminophenylthio]butadiene) was identified as an inhibitor of AP-1 transactivation in a cell-based reporter assay. U0126 was also shown to inhibit endogenous promoters containing AP-1 response elements

Coordinate Regulation of IκB Kinases by Mitogen-Activated Protein Kinase Kinase Kinase 1 and NF-κB-Inducing Kinase [PDF]

Molecular and Cellular Biology, 1998
IkappaB kinases (IKKalpha and IKKbeta) are key components of the IKK complex that mediates activation of the transcription factor NF-kappaB in response to extracellular stimuli such as inflammatory cytokines, viral and bacterial infection, and UV irradiation.

PD 098059 Is a Specific Inhibitor of the Activation of Mitogen-activated Protein Kinase Kinase in Vitro and in Vivo(*)

Journal of Biological Chemistry, 1995
PD 098059 has been shown previously to inhibit the dephosphorylated form of mitogen-activated protein kinase kinase-1 (MAPKK1) and a mutant MAPKK1(S217E,S221E), which has low levels of constitutive activity (Dudley, D. T., Pang, L., Decker, S.

Protein Kinase Mitogen-activated Protein Kinase Kinase Kinase Kinase 4 (MAP4K4) Promotes Obesity-induced Hyperinsulinemia [PDF]

Journal of Biological Chemistry, 2016
Previous studies revealed a paradox whereby mitogen-activated protein kinase kinase kinase kinase 4 (Map4k4) acted as a negative regulator of insulin sensitivity in chronically obese mice, yet systemic deletion of Map4k4 did not improve glucose tolerance.
