Insulin receptor (INSR) is a transmembrane receptor tyrosine kinase that plays a central role in mediating the effects of insulin on glucose homeostasis and metabolism. Structurally, the mature receptor is a tetramer composed of two extracellular α-subunits, responsible for insulin binding, and two transmembrane β-subunits, which possess intrinsic tyrosine kinase activity and mediate intracellular signaling upon insulin binding. The INSR gene undergoes alternative splicing to produce two main isoforms, IR-A and IR-B, which differ in their tissue distribution and functional properties. Upon insulin binding, the receptor undergoes autophosphorylation and activates downstream signaling pathways that regulate glucose uptake, lipid metabolism, cell growth, and survival. Dysfunction or mutations in INSR can impair insulin signaling, leading to insulin resistance and contributing to metabolic disorders such as type 2 diabetes and, less commonly, rare syndromes of severe insulin resistance; aberrant signaling is also implicated in certain cancers due to its role in cell proliferation and apoptosis.
