Other Information

**Key Characteristics** IRS4 is a 140-kDa phosphoprotein, belonging to the insulin receptor substrate family. It is highly expressed in various cell types, including hematopoietic cells, endothelial cells, and immune cells such as macrophages and dendritic cells. IRS4 is characterized by its ability to interact with multiple signaling molecules, including the insulin receptor, phosphatidylinositol 3-kinase (PI3K), and the type 1 insulin-like growth factor receptor (IGF1R). This multifunctional nature of IRS4 enables it to regulate a wide range of cellular processes, including glucose metabolism, cell growth, and differentiation. **Pathways and Functions** IRS4 is integral to the insulin signaling pathway, which is crucial for maintaining glucose homeostasis. Upon insulin binding to the insulin receptor, IRS4 is phosphorylated and activated, triggering a cascade of downstream signaling events that regulate glucose uptake, glycogen synthesis, and lipogenesis. The IRS4-PI3K pathway is also involved in cell survival and apoptosis, with IRS4 acting as a negative regulator of apoptosis. Additionally, IRS4 interacts with the IGF1R pathway, which is involved in cell growth and differentiation. The functions of IRS4 are multifaceted, including: * Glucose metabolism: IRS4 regulates glucose uptake, glycogen synthesis, and lipogenesis in response to insulin. * Cell survival: IRS4 acts as a negative regulator of apoptosis, promoting cell survival in response to insulin. * Cell growth: IRS4 regulates cell growth and differentiation in response to insulin and IGF1R signaling. * Immune function: IRS4 is expressed in immune cells, where it regulates immune responses and inflammation. **Clinical Significance** Dysregulation of the IRS4 pathway has been implicated in various metabolic disorders, including insulin resistance, type 2 diabetes, and metabolic syndrome. Mutations in the IRS4 gene have been associated with congenital insulin resistance, a rare genetic disorder characterized by impaired glucose metabolism and insulin resistance. Furthermore, IRS4 has been shown to play a role in the pathogenesis of other diseases, including: * Cancer: IRS4 is overexpressed in various types of cancer, including breast, lung, and colon cancer, where it promotes cell growth and survival. * Atherosclerosis: IRS4 is involved in the development of atherosclerosis, a cardiovascular disease characterized by inflammation and lipid accumulation in the arterial wall. * Autoimmune diseases: IRS4 has been implicated in the pathogenesis of autoimmune diseases, including rheumatoid arthritis and lupus, where it regulates immune responses and inflammation. In conclusion, IRS4 is a critical component of the insulin signaling pathway, playing a pivotal role in glucose metabolism, cell survival, and immune function. Dysregulation of the IRS4 pathway has been implicated in various metabolic disorders and diseases, highlighting its importance as a therapeutic target for the treatment of these conditions.

Database document:

This is a preview of the gene's schema. Only a few entries are kept for 'singleCellExpressions,' 'mRNAExpressions,' and other large data arrays for visualization purposes. You can zoom in with the mouse wheel for a closer view, and the text will adjust automatically if necessary. For the full schema, download it here.
