LAT is a transmembrane molecule that mediates signaling following the engagement of a number of cell surface receptors including TCR during mature T cell activation, pre-TCR during T cell development, Fc RIII on NK cells, and FcεRI on mast cells.LAT is multiply phosphorylated on tyrosines by ZAP-70 and Syk, which leads to downstream effects that include release of intracellular calcium, PKC activation, MAPK activation and cytoskeletal reorganization.Palmitoylation of LAT is required for its localization to lipid rafts and efficient phosphorylation.Product Details

WB - Quality tested
- Recommended Usage
Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.2 - 1.0 µg per ml. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
This clone may recognize a ~80 kD protein of unknown origin in some cell lines and tissue homogenates. It is also predicted to recognize rat LAT due to complete sequence homology between human, mouse, and rat LAT.

- Type III transmembrane protein, MW of 28 kD but expected at 36-38 kD due to post-translational modifications including palmitoylation; multiple isoforms with a predicted MW of 25-28 kD reported.
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).
- LAT is required for signaling through a number of cell surface receptors including TCR, FcγRIII, and FcεRI.
- Interacts directly with GRB2, GRAP, GRAP2, PLCG1 and PLCG2. Interacts indirectly with CBL, SOS, VAV, LCP2, SHB, SKAP2, MIST,and FcγR1A
