Diabetes, 1972
Studies with bulky and insoluble insulin derivatives indicate that this hormone can activate various metabolic processes by interaction with cell surface structures. A definition of “receptor” is offered which is operationally useful in studies directed to the identification and purification of receptor structures.

The insulin receptor endocytosis
2023Insulin signaling controls multiple aspects of animal physiology. At the cell surface, insulin binds and activates the insulin receptor (IR), a receptor tyrosine kinase. Insulin promotes a large conformational change of IR and stabilizes the active conformation.

Insulin Receptors, Receptor Antibodies, and the Mechanism of Insulin Action
1981Publisher Summary Insulin exerts a wide spectrum of effects at the cellular level. These include effects at the membrane level, for example, the stimulation of glucose and amino acid uptake; effects on both membrane and cytoplasmic enzymes; and effects on protein synthesis, DNA synthesis, cell growth, and differentiation.

Insulin Receptors and Insulin Resistance
Annual Review of Medicine, 1983Resistance to the action of insulin plays a central role in many important disease states, including diabetes and obesity. Many insights into the mechanism and significance of insulin resistance in these and other disorders have followed upon our expanding knowledge regarding insulin receptors.

THE ERYTHROCYTE INSULIN RECEPTOR
Australian Journal of Experimental Biology and Medical Science, 1981SummaryA precise, reproducible radioreceptor assay has been developed for insulin receptors on human erythrocytes. The mean specific binding in 11 normal volunteers was 7.7% ± 1.6 (S.D.) per 2.25 × 109 erythrocytes. The intra and inter assay coefficients of variation are 4%.

Publisher Summary This chapter focuses on insulin receptors in brain. It has been demonstrated by two different means that insulin from blood can reach the cerebrospinal fluid and then, presumably, the central nervous system tissue. While the access of circulating insulin is quite limited by the presence of the blood–brain barrier, the non-barrier ...

Insulin Receptor Antibodies and Insulin Resistance
Southern Medical Journal, 1999The presence of insulin receptor antibodies is a rare cause of insulin resistance. Patients usually have a combination of hyperglycemia, insulin resistance, acanthosis nigricans, and autoimmune features. We report a patient with systemic lupus erythematosus and severe insulin resistance due to insulin receptor antibodies.

Autoantibodies to insulin receptors
Molecular and Cellular Endocrinology, 1981In summary, these studies using antibodies to the insulin receptor have provided some new insights into the structure of the insulin receptor and the action of insulin itself. They suggest that most of insulin's actions are mediated through a common pathway and these can be initiated by interaction of ligands other than insulin with the insulin ...

Biochimie, 1985
The insulin receptor appears as a tetrameric glycoprotein consisting of two Mr 130,000 subunits (alpha), and two Mr 95,000 subunits (beta) in a disulfide-linked complex. Insulin bound to its specific cell surface receptors in its target cells leads to a complex array of molecular events resulting in insulin effects.

Insulin receptors and the site of action of insulin
Life Sciences, 1978Abstract There is considerable evidence that insulin receptors located on the plasma membrane of target cells directly mediate the short- term effects of insulin on plasma membrane functions such as glucose transport. These receptors are composed of four subunits, contain two or more binding sites, and show features of negative cooperativity. Insulin
