OVERVIEW
DOCUMENTS/REFERENCES
Biological Information
Background Information:
ZA70 (Tyrosine Protein kinase ZAP-70, 70 kDa zeta-associated protein, Syk-related tyrosine kinase) is a cytosolic protein tyrosine kinase (PTK) and a member of the Syk family of proteins. ZA70 is expressed in human and murine thymocyte subsets, B cells, and peripheral T cell subsets and associates with zeta-chain to undergo tyrosine phosphorylation following TCR stimulation. ZA70 inhibitors may be useful as immunosuppressants.

Testing Information
Procedure Summary:
Human recombinant protein kinase ZAP-70 expressed in insect cells is used. Test compound and/or vehicle is preincubated with 0.45 U/ml enzyme‡ for 15 minutes at 37°C in modified HEPES buffer pH 7.4. The reaction is initiated by addition of 0.2 mg/ml poly(Glu:Tyr), 10 µM ATP containing 0.25 µCi [γ32P]ATP for 30 minutes and terminated by further addition of 3% H3PO4. An aliquot is counted to determine the radioactivity of [32P]Poly(Glu:Tyr). Compounds are screened at 10 µM.
