ZAP70 Kinase Enzyme System, Promega
Supplier: Promega Corporation
Recombinant full-length human ZAP70 was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. ZAP70 is a nonreceptor protein tyrosine kinase (part of the Syk/Zap70 family) that is involved in signaling by the T-cell antigen receptor.
- Easily Screen and Profile ZAP70 Kinase Inhibitors
- Includes kinase, substrate and reaction buffer
- Use with ADP-Glo™ Assay for bioluminescent detection of kinase activity
Recombinant full-length human ZAP70 was expressed by baculovirus in Sf9 insect cells using an N-terminal GST tag. ZAP70 is a nonreceptor protein tyrosine kinase (part of the Syk/Zap70 family) that is involved in signaling by the T-cell antigen receptor (TCR). Ligation of the TCR/CD3 receptor in Jurkat T-cells induces phosphoprotein complexes, which contain ZAP70. TCR zeta chains are initially phosphorylated by p56Lck that lead to the recruitment of ZAP70 via its SH2 domain. ZAP70 in turn phosphorylates other proteins in the TCR-phosphoprotein complex. One of the natural substrates for ZAP70 is the zeta-chain dimer of the TCR/CD3 complex. ADP-Glo Kinase Assay is a luminescent kinase assay that measures ADP formed from a kinase reaction; ADP is converted into ATP, which is a substrate in a reaction catalyzed by Ultra-Glo Luciferase that produces light. The luminescent signal positively correlates with ADP amount and kinase activity. The assay is well suited for measuring the effects chemical compounds have on the activity of a broad range of purified kinases, making it ideal for both primary screening as well as kinase selectivity profiling. The ADP-Glo Kinase Assay can be used to monitor the activity of virtually any ADP-generating enzyme (e.g., kinase or ATPase) using up to 1mM ATP. Kinase Enzyme System contains: Kinase: ZAP70, 10ug (Human, recombinant full-length). MW: ~96kDa. Substrate: Poly (4:1 Glu, Tyr) Peptide. Other: Reaction Buffer, DTT, MnCl2.
