LAT Antibody | anti-LAT antibody

LAT (Phospho-Tyr191) Antibody

Cat. Num. AAA8509468

• Gene Names: LAT; LAT1; pp36; IMD52
• Reactivity: Human, Mouse, Rat
• Applications: Western Blot, Immunohistochemistry, ELISA
• Purity: Affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
• Synonyms: LAT; LAT (Phospho-Tyr191) Antibody; 36 kDa phospho-tyrosine adaptor protein; Linker for activation of T cells; p36-38; pp36; anti-LAT antibody

• Reactivity: Human, Mouse, Rat
• Specificity: LAT (Phospho-Tyr191) antibody detects endogenous levels of LAT only when phosphorylated at tyrosine 191.
• Purity/Purification: Affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
• Form/Format: In phosphate buffered saline (without Mg2+ and Ca2+), pH 7.4, 150mM NaCl, 0.02% sodium azide and 50% glycerol.
• Sequence Length: 233

• Applicable Applications for anti-LAT antibody: Western Blot (WB), Immunohistochemistry (IHC), ELISA (EIA)
• Application Notes: WB: 1:500~1:1000; IHC: 1:50~1:100; ELISA: 1:1000
• Immunogen: The antiserum was produced against synthesized phosphopeptide derived from human LAT around the phosphorylation site of tyrosine 191 (R-E-YP-V-N).
• All Sites: Human: Tyr191; Mouse: Tyr195; Rat: Tyr195
• Preparation and Storage: Store at-20 degree C for 1 year.

NCBI Description

The protein encoded by this gene is phosphorylated by ZAP-70/Syk protein tyrosine kinases following activation of the T-cell antigen receptor (TCR) signal transduction pathway. This transmembrane protein localizes to lipid rafts and acts as a docking site for SH2 domain-containing proteins. Upon phosphorylation, this protein recruits multiple adaptor proteins and downstream signaling molecules into multimolecular signaling complexes located near the site of TCR engagement. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

Uniprot Description

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.
