| Size | 100 µl |
| Reactivity | H M |
| Sensitivity | Endogenous |
| Molecular Weight (kDa) | 40 |
| Source/Isotype | Rabbit |
| Application/Dilution | {Western Blotting: 1:1000, Immunoprecipitation: 1:50} |
| Storage | Supplied in 10 mm sodium HEPES (pH 7.5), 150 mm NaCl, 100 µg/mL BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody. |
| Specificity/Sensitivity | Phospho-LAT (Tyr255) Antibody recognizes endogenous levels of LAT protein only when phosphorylated at Tyr255. Tyr255 of LAT, long isoform corresponds to Tyr226 of LAT, short isoform. |
| Species Reactivity | Human, Mouse |
| Source/Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Tyr255 of human LAT protein, isoform 1. Antibodies are purified by protein A and peptide affinity chromatography. |
| Background | LAT, 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).Research studies have shown that LAT is also phosphorylated at Tyr225 by ZAP-70 and Syk following activation of the TCR, which facilitates its binding to Grb2 and Vav and subsequent downstream activation of ERK (5-7). |
