Properties

  • Form

    Liquid
  • Storage instructions

    Shipped at 4°C. Upon delivery aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.
  • Storage buffer

    pH: 7.30
    Preservative: 0.05% Sodium azide
    Constituent: 0.1% BSA
  • Concentration information loading...
  • Purity

    Immunogen affinity purified
  • Purification notes

    Purified from rabbit serum by sequential epitope-specific chromatography. The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated LAT. The final product is generated by affinity chromatography using an LAT-derived peptide that is phosphorylated at tyrosine 132.
  • Clonality

    Polyclonal
  • Isotype

    IgG
  • Research areas

Target

  • Function

    Required for TCR (T-cell antigen receptor)- and pre-TCR-mediated signaling, both in mature T-cells and during their development. Involved in FCGR3 (low affinity immunoglobulin gamma Fc region receptor III)-mediated signaling in natural killer cells and FCER1 (high affinity immunoglobulin epsilon receptor)-mediated signaling in mast cells. Couples activation of these receptors and their associated kinases with distal intracellular events such as mobilization of intracellular calcium stores, PKC activation, MAPK activation or cytoskeletal reorganization through the recruitment of PLCG1, GRB2, GRAP2, and other signaling molecules.
  • Tissue specificity

    Expressed in thymus, T-cells, NK cells, mast cells and, at lower levels, in spleen. Present in T-cells but not B-cells (at protein level).
  • Post-translational
    modifications

    Phosphorylated on tyrosines by ZAP-70 upon TCR activation, or by SYK upon other immunoreceptor activation; which leads to the recruitment of multiple signaling molecules. Is one of the most prominently tyrosine-phosphorylated proteins detected following TCR engagement. May be dephosphorylated by PTPRJ.
    Palmitoylation of Cys-26 and Cys-29 is required for raft targeting and efficient phosphorylation.
  • Cellular localization

    Cell membrane. Present in lipid rafts.

Images

  • Peptide Competition
    Extracts prepared from Jurkat E6.1 cells were left unstimulated (1) or stimulated (2-5), resolved by SDS-PAGE on a 10% polyacrylamide gel, and transferred to PVDF. Membranes were blocked with a 5% BSA-TBST buffer overnight at 4°C, then were incubated with 0.35 µg/ml phospho LAT (Tyr 132) antibody for two hours at room temperature in a 3% BSA-TBST buffer, following prior incubation with: no peptide (1, 2), the nonphosphopeptide corresponding to the immunogen (3), a generic phosphotyrosine containing peptide (4), or, the phosphopeptide immunogen (5). After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG alkaline phosphatase and signals were detected using the Tropix WesternStar method. The data show that only the peptide corresponding to phospho LAT (Tyr 132) completely blocks the antibody signal, thereby demonstrating the specificity of the antibody, and stimulation-induced tyrosine phosphorylation of phospho LAT (Tyr 132).
