Product Specific Information
Antibody detects endogenous levels of LAT only when phosphorylated at Tyr220, which site historically referenced as Tyr191.
Target Information
LAT (Linker for Activation of T cells) is a 36–38 kDa double-palmitoylated transmembrane adaptor protein expressed by T cells, pre-B cells, NK cells, mast cells, and platelets. After immunoreceptor triggering, LAT becomes multiply tyrosine-phosphorylated by Syk-, Src-, or Tec-family kinases, providing docking sites for downstream signaling molecules. LAT is essential for TCR-dependent T cell and FcεRI-dependent mast cell activation, as well as for maturation of early thymocytes. It also plays roles in NK cell signaling and platelet activation.
