insulin receptor

Also found in: Acronyms, Wikipedia.


A gene on chromosome 19p13.3-p13.2 that encodes insulin receptor, the binding of insulin to which stimulates glucose uptake.

Molecular pathology
Defects of INSR cause Rabson-Mendenhall syndrome, leprechaunism and hyperinsulinaemic hypoglycaemia type 5.

insulin receptor

A heterodimeric membrane receptor composed of α and
β chains, which has tyrosine kinase activity after binding insulin; IR deficiency is a rare cause of DM and may be due to a gene rearrangement, causing a deletion in the tyrosine kinase domain, a point mutation with a loss of the ATP binding site or other genetic defect

Among the intracellular substrates used by these receptors, six belong to the insulin receptor substrate family (IRS1-6) (15), which act as docking molecules for proteins containing SH2 domains, while permitting downstream signal transmission; IRS1 and IRS2 are ubiquitously expressed and are the main mediators of insulin-dependent mitogenic activity and of the regulation of glucose metabolism in most cell types (16); other substrates are the isoforms of adapting proteins Cbl, Shc, Gab 1/2, and members of the APS family (adapting proteins with PH and SH2 domains).
