Immunogen
Synthetic peptide derived from a region of human ZAP70 that contains tyrosine 292 (unfortunately, the amino acid sequence is considered to be commercially sensitive)
Positive control
Jurkat cells treated with hydrogen peroxide.

Purity
Immunogen affinity purified
Purification notes
The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated ZAP70. The final product is generated by affinity chromatography using a ZAP70-derived peptide that is phosphorylated at threonine 292.

Applications
Show applications key
Our Abpromise guarantee covers the use of ab12868 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
WB: 1/1000Predicted molecular weight: 74.3 kDa.
Target
Function
Plays a role in T-cell development and lymphocyte activation. Essential for TCR-mediated IL-2 production. Isoform 1 induces TCR-mediated signal transduction, isoform 2 does not.
Tissue specificity
Expressed in T- and natural killer cells.
Involvement in disease
Defects in ZAP70 are the cause of selective T-cell defect (STD) [MIM:176947]. STD is an autosomal recessive form of severe combined immunodeficiency characterized by a selective absence of CD8-type T-cells.
Sequence similarities
Belongs to the protein kinase superfamily. Tyr protein kinase family. SYK/ZAP-70 subfamily.
Contains 1 protein kinase domain.
Contains 2 SH2 domains.
Domain
The SH2 domains bind to the phosphorylated tyrosine-based activation motif (TAM) of CD3Z and the non-canonical phosphorylated tyrosine-based activation motif (TAM) of RHOH.
Post-translational
modifications
Phosphorylated on tyrosine residues upon T-cell antigen receptor (TCR) stimulation. Tyr-319 phosphorylation is essential for full activity.
Cellular localization
Cytoplasm. Cell membrane. After antigen stimulation, isoform 1 concentrates at the immunological synapse and isoform 2 remains cytoplasmic. Co-localizes together with RHOH in the immunological synapse. RHOH is required for its proper localization to the cell membrane and cytoskeleton fractions in the thymocytes.

Western blot - ZAP70 (phospho Y292) antibody (ab12868)
Predicted band size : 74.3 kDa
Peptide Competition and Phosphatase Treatment: Lysates prepared from Jurkat cells left untreated (1) or treated with hydrogen peroxide (2-6) were either left untreated (1-5) or treated with lambda phosphatase (6). Lysates were then incubated with ab12868 following prior incubation with: no peptide (1, 6), the non-phosphopeptide corresponding to the immunogen (2), a generic phosphotyrosine-containing peptide (4) or, the phosphopeptide immunogen (5). The data show that only the peptide corresponding to ZAP70 [phospho Y292] blocks the antibody signal. The data also show that phosphatase stripping eliminates the signal, verifying that the antibody is phospho-specific.
