Insulin receptor substrates (IRS) are responsible for several insulin related activities, such as glucose homeostasis, cell growth, cell transformation, apoptosis and insulin signal transduction. Serine/threonine phosphorylation of IRS-1 has been demonstrated to be a negative regulator of insulin signaling and is responsible for its degradation, although IRS-1 degradation pathways are not well understood. IRS-1 has also been shown to be constitutively activated in cancers such as breast cancer, Wilm's tumors, and adrenal cortical carcinomas, thus making IRS-1 phosphorylation and subsequent degradation an attractive therapeutic option. To date there have been four subtypes identified: IRS-1,2,3, and 4, with IRS-1 being widely expressed.
