Essentially identical proteins in mammals (p38 MAP Kinases) and yeast (HOG-1). Inhibitors include protein phosphatase 2A, PTP-1B, CL-100 and pyridinyl imidazols.
Activated using a constitutively active mutant of MKK6 and repurified using glutathione sepharose.
Recombinant protein corresponding to human SAPK2b, fused to GST-Tag at N-terminal, expressed in E. coli.
Molecular Weight:~65kD
Specific Activity:143U/mg
Unit Definition:One unit of SAPK2b activity is defined as 1nmol phosphate incorporated into 0.33mg/ml myelin basic protein (MBP) per minute at 30°C with a final ATP concentration of 100uM.
Applications:Coupled Kinase Assay: Enzyme was tested in vitro in a coupled kinase phosphorylation assay using 20-100ng of active SAPK2b to activate GST-MAPKAP Kinase-2, unactivated as shown by phosphorylation of MAPKAP Kinase-2 Substrate Peptide.
Storage and Stability:May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 6 months after receipt at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
