Characteristics 1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.
2. Source of all serum proteins is from USDA inspected abattoirs located in the United States.
3. Caution: Sodium azide yields highly toxic hydrazoic acid under acidic conditions. Dilute azide compounds in running water before discarding to avoid accumulation of potentially explosive deposits in plumbing.
4. Please refer to us for technical protocols.
Purification Purified from tissue culture supernatant or ascites by affinity chromatography.
Alternative Name ZAP-70
Background ZAP-70 is a protein tyrosine kinase (PTK) that associates with the zeta subunit of the T cell antigen receptor (TCR) and undergoes tyrosine phosphorylation following TCR stimulation. ZAP-70 contains two SH2-like domains with the PTK domain being at the C-terminus. It appears that both ZAP-70 and Syk are recruited to the phosphorylated CD3 and zeta subunits after TCR stimulation. The src-family PTKs, lck, and fyn, seem to play a role upstream of ZAP-70 and Syk where they phosphorylate CD3 and zeta. Thus both Src- and ZAP-70/Syk-family PTKs are critical for efficient induction of tyrosine phosphoproteins in heterologous cells. The significance of ZAP-70 in mediating TCR signal transduction has been confirmed by showing that ZAP-70 activity is absent in an autosomal recessive form of severe combined immunodeficiency (SCID). This is due to mutations affecting the ZAP-70 kinase domain which affect the stability of the protein. The levels of lck and fyn appear to be normal in the same cells. Results of the ZAP-70 mutations in these patients include an unusual absence of peripheral CD8+ T cells and an abundance of CD4+ T cells in peripheral lymphoid organs. These results indicate that these two populations of T cells develop through utilization of different intracellular signaling pathways.
