Tyr220 of LAT, long isoform corresponds to Tyr191 of LAT, short isoform. Weak cross-reactivity with phosphorylated tyrosines 171 and 255 of LAT has been observed.\nSpecies Reactivity: Human\n\u003cb\u003eSource \/ Purification\u003c\/b\u003e\nPolyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues around Tyr220 of human LAT. Antibodies are purified by protein A and peptide affinity chromatography.\n\u003cb\u003eBackground\u003c\/b\u003e\nLAT, a transmembrane adaptor protein expressed in T, NK, and mast cells, is an important mediator for T cell receptor (TCR) signaling (1). Upon TCR engagement, activated Zap-70 phosphorylates LAT at multiple conserved tyrosine residues within SH2 binding motifs, exposing these motifs as the docking sites for downstream signaling targets (2,3). The phosphorylation of LAT at Tyr171 and Tyr220 enables the binding of Grb2, Gads\/SLP-76, PLCγ1, and PI3 kinase through their SH2 domain and translocates them to the membrane. This process eventually leads to activation of the corresponding signaling pathways (1-4).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\n36 kDa phospho-tyrosine adapter protein; 36 kDa phospho-tyrosine adaptor protein; IMD52; LAT; LAT1; linker for activation of T cells; linker for activation of T cells, transmembrane adaptor; Linker for activation of T-cells family member 1; p36-38; pp36\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H\nSENSITIVITY: Endogenous\nMW (kDa): 36, 38\nSOURCE: Rabbit","brand":"CST","offers":[{"title":"Default Title","offer_id":46799433466025,"sku":"3584T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-3584t","provider":"Iright","version":"1.0","type":"link"}
