Effect of insulin receptor autophosphorylation on insulin receptor binding
Molecular and Cellular Endocrinology, 1986Insulin receptor beta-subunit autophosphorylation, the first event occurring after insulin binding, plays a crucial role in modulation of receptor-associated kinase activity towards exogenous substrates and possibly in the transmission of biological signals of insulin. Receptor autophosphorylation strongly depends on insulin receptor occupancy.

The insulin receptor and the kidney
Current Opinion in Nephrology and Hypertension, 2013In recent years, it has become clear that the insulin receptor is important in a variety of renal cell types. It is through this transmembrane receptor that insulin, and to a lesser extent insulin-like growth factor, hormones bind and can control important cellular functions.

Insulin Receptor Isoforms and Insulin Receptor/Insulin-Like Growth Factor Receptor Hybrids in Physiology and Disease [PDF]
Endocrine Reviews, 2009 In mammals, the insulin receptor (IR) gene has acquired an additional exon, exon 11. This exon may be skipped in a developmental and tissue-specific manner. The IR, therefore, occurs in two isoforms (exon 11 minus IR-A and exon 11 plus IR-B). The most relevant functional difference between these two isoforms is the high affinity of IR-A for IGF-II.

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.
