IRS1

IRS1 (Insulin Receptor Substrate 1): IRS1 is a pivotal signaling molecule involved in mediating the cellular response to insulin and various growth factors. It acts as an adaptor protein, linking activated insulin receptors to downstream signaling pathways. Through its interaction with multiple intracellular signaling molecules, IRS1 regulates key cellular processes such as glucose uptake, glycogen synthesis, protein synthesis, and cell growth and proliferation. Dysregulation of IRS1 signaling is implicated in insulin resistance, a hallmark of type 2 diabetes and other metabolic disorders, as well as in cancer and cardiovascular diseases. The intricate network of IRS1-mediated signaling pathways underscores its significance...
