Product details:
Biological actions of insulin are mediated by the Insulin Receptor (IR), a receptor tyrosine kinase that regulates multiple signaling pathways through activation of a series of phosphorylation cascades. The IR is a heterotetrameric protein consisting of two ligand-binding alpha subunits and two beta subunits that each contain a tyrosine kinase domain. Insulin binding to the extracellular domain leads to autophosphorylation of the receptor and activation of the intrinsic tyrosine kinase activity, which allows appropriate substrates to be phosphorylated. Tyrosine 972 is in the juxtamembrane Asn-Pro- Glu-Tyr (NPEY) motif. Phosphorylation of IR tyrosine 972 is required for the binding and/or phosphorylation of the adapter protein Shc, the PTB domain, IRS-1, PI3 kinase, and the Suppressor of Cytokine Signaling (SOCS).

The insulin receptor (INSR) is a transmembrane glycoprotein that functions as a receptor for insulin. Known also as CD220 the receptor has a molecular weight of about 320 kDa. It is widely expressed in insulin-sensitive tissues such as liver muscle and adipose tissues. The insulin receptor consists of two α subunits and two β subunits forming a heterotetramer. These subunits are located outside and inside the cell membrane respectively. The α subunits bind insulin while the β subunits possess tyrosine kinase activity important for downstream signaling.
Biological function summary
Insulin receptor plays a role in facilitating the effects of insulin on glucose and lipid metabolism. When insulin a protein binds to the insulin receptor it undergoes a conformational change that activates its intrinsic kinase activity. This activation further leads to tyrosine phosphorylation of intracellular targets resulting in modulation of cellular functions. Insulin receptor also participates in the formation of signaling complexes through interaction with substrates like insulin receptor substrate (IRS) proteins which are important for the transmission of the insulin signal inside cells.
Pathways
Insulin receptor is central to the insulin signaling pathway and the mitogen-activated protein kinase (MAPK) pathway. Activation of the insulin receptor triggers the insulin signaling cascade which involves various proteins like PI3 kinase and Akt that contribute to glucose uptake and metabolism. In the MAPK pathway the insulin receptor influences gene expression related to cell growth and differentiation. These pathways intertwine with other hormone signaling systems and affect numerous physiological processes critical for maintaining metabolic homeostasis.
Aberrations in insulin receptor function are linked to insulin resistance and type 2 diabetes. Defective signaling through this receptor impairs glucose transport into cells contributing to hyperglycemia. Disorders in insulin receptor activity also relate to metabolic syndrome a cluster of conditions increasing the risk of heart disease. Proteins connected to these conditions include IRS proteins and PI3 kinase highlighting the integrated roles these components play in metabolic regulation. Developing anti-insulin receptor antibodies offers potential therapeutic interventions to modulate receptor function and manage these disorders effectively.
