LAT Overexpression Lysate

HEK293T cells in 10-cm dishes were transiently transfected with a non-lipid polymer transfection reagent specially designed and manufactured for large volume DNA transfection. Transfected cells were cultured for 48hrs before collection. The cells were lysed in modified RIPA buffer (25mM Tris-HCl pH7.6, 150mM NaCl, 1% NP-40, 1mM EDTA, 1xProteinase inhibitor cocktail mix, 1mM PMSF and 1mM Na3VO4, and then centrifuged to clarify the lysate. Protein concentration was measured by BCA protein assay kit.

LAT (linker for activation of T-cells) is involved in the T-cell antigen receptor (TCR) signal transduction pathway, and may play an important role downstream in activating protein tyrosine kinases (1). LAT is phosphorylated by ZAP-70/Syk protein tyrosine kinases leading to recruitment of multiple signaling molecules (2). It has been found that Tyr191 and Tyr171 are required for T-cell activation and Tyr132 is required for the activation of PLCgamma1 and Ras signaling pathways, respectively. Tyr226 and Tyr191 are required for Vav binding, whereas Tyr171 and Tyr132 are necessary for association and activation of phosphoinositide 3-kinase activity and PLCgamma1 (3).
