Wortmannin is a potent and reversible inhibitor of insulin-stimulated PtdIns 3-kinase activity in 3T3-L1 cells (IC50 = 2.6 +/- 0.8 nM). Wortmannin inhibits the PtdIns 3-kinase activity which is precipitated with antibodies against insulin receptor substrate 1 and against the alpha-p85 subunit of PtdIns 3-kinase. These observations suggest that wortmannin inhibits at the p110 catalytic subunit of PtdIns 3-kinase. Insulin stimulation of glucose transport in permeabilized 3T3-L1 cells is also… CONTINUE READING
