erk2 2d 💯 SHANK3 depletion leads to ERK signalling overdose and cell Nature

erk2 2d - Differential contribution for ERK1 and ERK2 wallpaper muhammad 3d 14 kinases in Here we demonstrate that EGFRactivated ERK2 binds directly to PKM2 Ile 429Leu 431 through the ERK2 docking groove and phosphorylates PKM2 at Ser 37 but does not phosphorylate PKM1 Conformation selection by ATPcompetitive inhibitors and allosteric 2ERK PubMed Abstract The structure of the active form of the MAP kinase ERK2 has been solved phosphorylated on a threonine and a tyrosine residue within the phosphorylation lip The lip is refolded bringing the phosphothreonine and phosphotyrosine into alignment with surface argininerich binding sites Conformational changes occur in the Importantly BRAF V600Edependent ERK2 phosphorylation increase in ErkBRAF V600E mice is comparable to that one observed in the presence of ERK1 Fig 5A E thus suggesting that ERK1 depletion Extracellular signalregulated kinases associate with and Nature Largescale Discovery of ERK2 Substrates Identifies ERKMediated Modulating multifunctional ERK complexes by covalent Nature To further test this possibility we utilized solution NMR methodology taking advantage of the available assignments for backbone and methyl resonances of ERK2 4041 A 2D 15 N 1 H TROSYbased AS kinases retain their natural substrate specificity For instance ERK2 with Q103G substitution ASERK2 uses ATP and ATP analogs efficiently and interacts with known ERK2 substrates and an AS form of cyclindependent kinase 2 ASCDK2 retains the kinetics and substrate specificity of the wildtype protein Radioactive tagging on γ LargeScale

ATPcompetitive inhibitors and eLife Quantitative StructureActivity Relationship QSAR models typically rely on 2D and 3D molecular descriptors to characterize chemicals and forecast their experimental activities Previously we showed that even the most reliable 2D QSAR models and structurebased 3D molecular docking techniques were not capable of accurately ranking a set of known inhibitors for the ERK2 kinase a key player NMR spectroscopy was used to test the effect of inhibitors on conformational exchange in 2PERK2 2D 13 C 1 HHMQC spectra were collected on complexes of ERK2 with BVD523 and VTX11e which share chemical features including a central amidolinked pyrrole scaffold and GDC0994 which has a distinct central pyridone scaffold Figure 2A Figure Interestingly S984 was sensitive to above ERK2 mutations Fig 2D center plot This phenomenon could be explained by the crystal structure of S984ERK2 complex PDB 4QTB Unlike VI3 which binds underneath the Gloop the long

background level on the ELK1 mut template Fig 2d Supplementary Fig 1C Figures and data in Conformation selection by ATPcompetitive eLife Preliminary processing of the collected dataset and inspection of initial twodimensional 2D classes indicated that ERK2 could interact with DHPS in various stoichiometries Because the active form of DHPS is a tetramer up to 14 complex stoichiometry ie 1 DHPS tetramer to 4 ERK2 molecules is feasible For instance ERK2 with Q103G substitution ASERK2 uses ATP and ATP analogs efficiently and interacts with known ERK2 substrates and an AS form of
