insulin receptor
INSR
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 andβ 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
