      Overview

      This product has been discontinued.



      Recombinant, human PERK consisting of amino acids 563-1115 fused at the N-terminus to GST and expressed in E. coli. PERK phosphorylates the α-subunit of eukaryotic translation initiation factor 2 (EIF2α), which leads to its inactivation and reduces translation initiation. The active kinase is useful for the study of PERK regulation and for inhibitor screening.
      Note: the calculated MW is 88,000, but the protein runs at ~115,000 on SDS-PAGE.

      Concentration Label Please refer to vial label for lot-specific concentration
      Recommended reaction conditions
      Kinase assay conditions: Dilute purified PERK in kinase dilution buffer (5 mM MOPS, pH 7.2, 4 mM MgCl2, 2.5 mM β-glycerophosphate, 1 mM EGTA, 400 µM EDTA, 50 ng/µl BSA, 5% glycerol; add DTT to 50 µM just prior to use) to the desired concentration. Mix 10 µl diluted enzyme, 5 µl SMAD3 substrate (200 ng/ml stock), and 5 µl H2O and incubate for 5 min at 30°C. Add 5 µl ATP mixture [(150 µl of 10 mM ATP, 100 µl of 1 mCi/100µl [32P]ATP, and 5.75 ml kinase assay buffer (25 mM MOPS, pH 7.2, 25 mM MgCL2, 12.5 mM β-glycerophosphate, 5 mM EGTA, 2 mM EDTA with 250 µM DTT just prior to use)] and incubate for 15 min at 30°C. Terminate the reaction by spotting 20 µl of the reaction mixture onto a phosphocellulose P81 paper, dry, and wash several times with 1% phosphoric acid prior to counting in the presence of scintillation fluid.
