Western Blot analysis of human PBMC with LAT monoclonal antibody, clone LAT1111 (Cat # MAB12960) followed by HRP-conjugated goat anti-mouse secondary antibody and visualized by chemiluminescence detection system.
The protein encoded by this gene is phosphorylated by ZAP-70/Syk protein tyrosine kinases following activation of the T-cell antigen receptor (TCR) signal transduction pathway. This transmembrane protein localizes to lipid rafts and acts as a docking site for SH2 domain-containing proteins. Upon phosphorylation, this protein recruits multiple adaptor proteins and downstream signaling molecules into multimolecular signaling complexes located near the site of TCR engagement. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq
