Description
OverviewRecombinant, mouse MAP Kinase 2 expressed in E. coli. A serine/threonine protein kinase that acts at the end of a protein kinase cascade linking signals from cell surface receptor tyrosine kinases to cytoplasmic and nuclear events. This protein was co-expressed with MEK and is phosphorylated and active.

Recommended reaction conditions
Note: This protocol is provided only as a general guide. Researchers should standardize this assay for their own specific needs and should consult published literature. Suggested Protocol to Assay for MAPK Activators 1. Combine the following on ice: 4.0 µl 250 mM HEPES, pH 7.5, 100 mM Mg(OAc)2, 500 µM ATP 2.0 µl MAP Kinase 1-29 µl purified MEK (cell lysates or fractions from chromatography) 2.0 µl [γ-32P]ATP (1.0 µCi/µl) add enough distilled H2O to produce a final volume of 40 µl. 2. Incubate at 30°C for 30 min. 3. Stop the reaction by adding 40 µl of 2X SDS-PAGE sample buffer. 4. The phosphorylated MAPK will show as a signal at ~45 kDa by autoradiography. Phosphorylating Protein Substrates with Phosphorylated MAPK 1. Combine the following on ice: 5.0 µl 500 mM Tris-HCl (pH 7.5), 62.5 mM β-glycerol phosphate, 50 mM MgCl2, 5 mM EGTA, 250 µM NaF, 5 mM DTT, and 2.5 mM sodium vanadate 2 µg experimental protein or Myelin Basic Protein Peptide Substrate (Cat. No. 475920) 1.0 µl phosphorylated MAPK 2.0 µl [γ-32P]ATP (1.25 mM,100 µCi/µmoll) add enough distilled H2O to produce a final volume of 25 µl. 2. Incubate at 30°C for 30 min. 3. Stop the reaction by spotting 20 µl of each reaction mixture onto a 1.5 cm2 piece of Whatman P81 paper. 4. Wash the squares 7X for 5 min with phosphoric acid (1% w/v). 5. Quantitate the 32P incorporation in a liquid scintillation counter.
