PA1-26640 detects LAT (phospho Y132) from human samples. PA1-26640 is expected to cross react with mouse (85% conserved), rat (77% conserved) due to sequence homology.
PA1-26640 has been successfully used in Western blot procedures.
The PA1-26640 immunogen is a synthetic phosphopeptide corresponding to a portion of human LAT containing tyrosine 132.
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 FcepsilonRI-dependent mast cell activation, as well as for maturation of early thymocytes. It is also involved in NK cell signaling and platelet activation.
