Description

Description: This n3kobu5 monoclonal antibody recognizes human and mouse zeta chain-associated protein of 70 kD (also known as ZAP-70) and spleen tyrosine kinase (also known as SYK) when phosphorylated on Y319 and Y352, respectively. ZAP-70 and SYK are members of the SYK protein tyrosine kinase (PTK) family that are phosphorylated and activated by Src family PTKs. ZAP-70/SYK Y319/Y352 are located in the so-called interdomain of ZAP-70/SYK (between the N-terminal dual SH2 domains and the C-terminal kinase domain). Phosphorylation of ZAP-70 Y319 by Lck is necessary for T cell receptor (TCR)-dependent association of ZAP-70 with Lck and phospholipase C gamma and subsequent activation of calcium-dependent and Ras signaling cascades. SYK Y352 phosphorylation by Fyn/Lyn is critical for propagation of B cell receptor (BCR) signaling and for B cell development. Specificity of this n3kobu5 clone was determined by ELISA, flow cytometry, and western blotting. Applications Reported: This n3kobu5 antibody has been reported for use in intracellular staining followed by flow cytometric analysis. Applications Tested: This n3kobu5 antibody has been pre-diluted and tested by intracellular staining and flow cytometric analysis of sodium pervanadate-treated mouse splenocytes using the Intracellular Fixation & Permeabilization Buffer Set (a href=https://www.thermofisher.com/order/catalog/product/88-8824-00>Product # 88-8824-00) and protocol.

ZAP-70 is a cytosolic protein tyrosine kinase that is a member of the Syk family of proteins. ZAP-70 is expressed exclusively in T-cells and natural killer cells and is required for T-cell receptor activation. Upon T cell antigen receptor (TCR) engagement, ZAP70 is phosphorylated on tyrosines 292, 315 and 319 in the interdomain B, located between the SH2 and kinase domains. Phosphorylation of both tyrosines 315 (a Vav binding site) and 319 (a Lck binding site) enhances ZAP70 function in mediating lymphocyte signaling, while tyrosine 292 terminates the transient activation of ZAP70 and attentuates lymphocyte signaling.
