IRS2 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.This product is manufactured by and sold under license from OriGene Technologies and its use is limited solely for research purposes.

Insulin receptor substrates (IRS), the major intracellular substrates of the insulin receptor (IR), are adaptor proteins that transduce signals from the IR to downstream effectors that are important for the biological effect of insulin (1-2). After insulin stimulation, IRS proteins are rapidly phosphorylated on multiple tyrosine residues. Once phosphorylated, IRS proteins bind and activate Grb-2, SHP2 and the PI3-K p85 subunit (2-3). Sequences of IRS-2 and IRS-1 reveal a highly conserved amino terminus containing a pleckstrin-homology domain and a phosphotyrosine-binding domain, and a poorly conserved carboxy terminus containing several tyrosine phosphorylation motifs. IRS-2 is expressed in many cells, including tissues from IRS-1-/- mice, and may be essential for signaling by several receptor systems such as insulin and cytokine (1).
