Human PTK2 (NP_722560.1, 1 a.a. - 527 a.a.) full-length recombinant protein with GST tag co-expressed with His-tagged WNK1 (NP_061852.1, 1 a.a. - 491 a.a.) expressed in Baculovirus infected Sf21 cells.
Theoretical MW (kDa):
Baculovirus infected insect cell (Sf21) expression system
Glutathione sepharose chromatography
62 % 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 : Blk/Lyntide. ATP: 100 µM.
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.
This gene encodes a cytoplasmic protein tyrosine kinase which is found concentrated in the focal adhesions that form between cells growing in the presence of extracellular matrix constituents. The encoded protein is a member of the FAK subfamily of protein tyrosine kinases but lacks significant sequence similarity to kinases from other subfamilies. Activation of this gene may be an important early step in cell growth and intracellular signal transduction pathways triggered in response to certain neural peptides or to cell interactions with the extracellular matrix. At least four transcript variants encoding four different isoforms have been found for this gene, but the full-length natures of only two of them have been determined. [provided by RefSeq
