    Protocol

    Specificity / Sensitivity

    Phospho-LAT (Tyr220) (E3S5L) Rabbit mAb recognizes endogenous levels of LAT protein when phosphorylated at Tyr220. This antibody shows cross-reactivity with phosphorylated EGFR, and detects a 70 kDa band of unknown origin in some treated cell lines. 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.

    Species Reactivity:

    Human, Mouse

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Tyr220 of human LAT protein.

    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).
