Human WNK2 (NP_006639.3, 166 a.a. - 489 a.a.) partial recombinant protein with GST tag expressed in baculovirus infected Sf21 cells.
Theoretical MW (kDa):
Baculovirus infected insect cell (Sf21) expression system
Glutathione sepharose chromatography and anion exchange chromatography
89 % by SDS-PAGE/CBB staining
The activity was measured by off-chip mobility shift assay. The enzyme was incubated with fluorescence-labeled substrate and Mg(or Mn)/ATP. The phosphorylated and unphosphorylated substrates were separated and detected by LabChip 3000. Substrate: SPAKtide. ATP: 100 uM.
Quality Control Testing:
Loading 1 ug protein in SDS-PAGE
In 50 mM Tris-HCl, 150 mM NaCl, pH 7.5 (0.05% Brij35, 1 mM DTT, 10% glycerol)
Store at -80°C. Aliquot to avoid repeated freezing and thawing.
The protein encoded by this gene is a cytoplasmic serine-threonine kinase that contains cysteine in place of the lysine found at the conserved ATP-binding location in subdomain II of protein kinases. Since this protein does have kinase activity, it is possible that another lysine in the kinase subdomain I can substitute for the missing conserved lysine. [provided by RefSeq
