enzyme mutants show embryonic lethality. Mkk4 knockout embryonic stem cells exhibit diminished p-ATF2 and MEF2C expression, resulting in impaired MHC induction and defective cardiomyocyte differdifferentiation. Loss of MKK4 significantly blocks the induction of Mhca and Mhcb, but had no effect on expression of Mlc. Exogenous MKK4 expression partially restores the ability of Mkk4-/- embryonic stem cells to differentiate into cardiomyocytes. Mice lacking either MKK4 or MKK7 display an analogous embryonic lethal phenotype that may be attributed, at least in part, to insufficient JNK activation; enzyme mutants show embryonic lethality. Mkk7 knockout embryonic stem cells show elevated phosphorylation of MKK4, p38, and ATF2, and increased MEF2C expression. The mutant cells show higher expression of MHC and MLC and enhanced formation of contractile cardiomyocytes.

mitogen-activated protein kinase kinase VdPbs2 is a key regulator of microsclerotia formation, oxidative stress and fungicide response and plant virulence in Verticillium dahliae via regulating the activity of VdHog1, a mitogen-activated protein kinase, MAPK. VdPbs2 and VdHog1 function in a cascade that regulates microsclerotia formation and virulence, but not all VdHog1 dependent functions are VdPbs2 regulated. VdPbs2 is essential for the oxidative stress response and is required for plant infection, VdPbs2 may be involved in the penetration process during plant infection

the transient state of apo npMAP2K4 exists between the canonical kinase fold and the aggregation state. The ATP molecule under physiological conditions allows the transient conformation to rapidly assume the canonical kinase fold but the depletion of ATP under conditions of low levels of bioactivity perhaps enhances the transition to the aggregation state

development of a continuous spectrophotometric assay for mitogen-activated protein kinase kinases. The assay relies on the measurement of phosphoprotein product generated in the first step of the MAPK kinase reaction. Dephosphorylation of the phosphoprotein is coupled to a MAPK phosphatase, MKP3, to generate phosphate, which is then used as the substrate of purine nucleoside phosphorylase to catalyze the N-glycosidic cleavage of 2-amino 6-mercapto 7-methyl purine ribonucleoside. Of the reaction products ribose 1-phosphate and 2-amino 6-mercapto 7-methylpurine, the latter has a high absorbance at 360 nm relative to the nucleoside and, hence, provides a spectrophotometric signal that can be continuously followed. In the presence of excess phosphatase, the phosphorylated protein substrate molecules undergo dephosphorylation almost immediately after their formation. The steady-state use of the resultant inorganic phosphate is a reflection of the constant initial velocity of the exchange reaction. Method development and evaluation, overview

design of small molecule MEK1/2 inhibitors to block ERK1/2-mediated signaling and inhibit proliferation. Four structurally distinct MEK1/2 inhibitors acutely affect mitochondrial bioenergetics. The anti-mitochondrial effects of MEK1/2 inhibitors determine the proliferative potential; design of small molecule MEK1/2 inhibitors to block ERK1/2-mediated signaling and inhibit proliferation.

SymRK acts as an inhibitor of SIP2 kinase activity when MPK6 is used as a substrate, suggesting that SymRK may serve as a negative regulator of the SIP2 signaling pathway. SymRK and SIP2 interact with each other but cannot use one another as a substrate for phosphorylation. SymRK can autophosphorylate itself but fails to phosphorylate the kinase-negative SIP2-KR, suggesting that SymRK is neither a potential phosphorylation target nor a kinase source of SIP2
