Abstract

Insulin induces a wide variety of growth and metabolic response in many cell types. Insulin initiates its biological effects by activation of tyrosine kinase in the beta-subunit and phosphorylates several proteins, such as insulin receptor substrate-1 (IRS-1), Shc. thereby activating phosphatidyl inositol 3-kinase activity, and ras activity. MAP kinase cascade activated by ras, 70kDaS6 kinase lying downstream of PI3-kinase, and the regulation of glycogen synthase have been discussed.
