Human MAP2K2 (NP_109587.1, 1 a.a. - 400 a.a.) full-length recombinant protein with GST tag expressed in baculovirus infected Sf21 cells.
Theoretical MW (kDa):
Baculovirus infected insect cell (Sf21) expression system
Glutathione sepharose chromatography
96 % by SDS-PAGE/CBB staining
The activity was determined by ELISA. The enzyme was incubated with GST-fused substrate protein, and after stopping kinase reaction by EDTA, the reaction solution was transferred into glutathione-coated plate. Phosphorylation was detected by anti-phospho antibody and HRP-labeled anti-rabbit IgG (or HRP-labeled anti-mouse IgG). Substrate: Erk2 [inactive mutant]. ATP: 100 uM.
Quality Control Testing:
Loading 1 ug protein in SDS-PAGE
In 50 mM Tris-HCl, 150 mM NaCl, pH 7.5 (0.1% CHAPS, 1 mM DTT, 10% glycerol)
Store at -80°C. Aliquot to avoid repeated freezing and thawing.
The protein encoded by this gene is a dual specificity protein kinase that belongs to the MAP kinase kinase family. This kinase is known to play a critical role in mitogen growth factor signal transduction. It phosphorylates and thus activates MAPK1/ERK2 and MAPK2/ERK3. The activation of this kinase itself is dependent on the Ser/Thr phosphorylation by MAP kinase kinase kinases. Mutations in this gene cause cardiofaciocutaneous syndrome (CFC syndrome), a disease characterized by heart defects, mental retardation, and distinctive facial features similar to those found in Noonan syndrome. The inhibition or degradation of this kinase is also found to be involved in the pathogenesis of Yersinia and anthrax. A pseudogene, which is located on chromosome 7, has been identified for this gene. [provided by RefSeq
