Species predicted to react based on 100% sequence homology: Rat.
Specificity / Sensitivity
LAT Antibody detects endogenous levels of total LAT protein.
Source / Purification
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the central region of human LAT. Antibodies are purified by protein A and peptide affinity chromatography.
Western blot analysis of extracts from Jurkat cells, untreated or treated with lambda phosphatase, using LAT Antibody.
Immunohistochemical analysis of paraffin-embedded Jurkat cells, using LAT Antibody in the presence of control peptide (left) or antigen-specific peptide (right).
Immunohistochemical analysis of paraffin-embedded human tonsil, showing membrane localization, using LAT Antibody.
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 Tyr191 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).
