Insulin receptor has tyrosine kinase activity toward Shc in rat liver
Brazilian Journal of Medical and Biological Research, 1998 Insulin induces tyrosine phosphorylation of Shc in cell cultures and in insulin-sensitive tissues of the intact rat. However, the ability of insulin receptor (IR) tyrosine kinase to phosphorylate Shc has not been previously demonstrated.

An insulin receptor mutant (Asp707 → Ala), involved in leprechaunism, is processed and transported to the cell surface but unable to bind insulin [PDF]
, 1996 We have identified a homozygous mutation near the carboxyl terminus of the insulin receptor (IR) α subunit from a leprechaun patient, changing Asp707 into Ala. Fibroblasts from this patient had no high affinity insulin binding sites.

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016 BackgroundIon transport in the renal proximal tubule (RPT), which is increased in essential hypertension, is regulated by numerous hormones and humoral factors, including insulin and dopamine. Activation of dopamine receptor inhibits sodium reabsorption,

Brefeldin A inhibits insulin-dependent receptor redistribution in HIRcB cells [PDF]
, 1995 Brefeldin A (BFA) is a potent inhibitor of intracellular vesicle traffic. We have investigated the effects of BFA on the traffic of the insulin receptor in HIRcB cells, a cell line derived from Rat-1 fibroblasts that over-expresses a normal human insulin

Activation of G proteins by GIV-GEF is a pivot point for insulin resistance and sensitivity. [PDF]
, 2015 Insulin resistance (IR) is a metabolic disorder characterized by impaired insulin signaling and cellular glucose uptake. The current paradigm for insulin signaling centers upon the insulin receptor (InsR) and its substrate IRS1; the latter is believed to

Žurnal Grodnenskogo Gosudarstvennogo Medicinskogo Universiteta, 2020 The mechanism of development of insulin resistance is not fully deciphered. Disorders that lead to insulin resistance can occur at the following levels of the insulin signaling pathway: pre-receptor (abnormal insulin), receptor (reduced number or affnity

Insulin receptor signaling regulates synapse number, dendritic plasticity, and circuit function in vivo [PDF]
, 2008 Insulin receptor signaling has been postulated to play a role in synaptic plasticity; however, the function of the insulin receptor in CNS is not clear.

Tissue-specific regulation of IRS-1 in unilaterally nephrectomized rats
Brazilian Journal of Medical and Biological Research, 1997 Insulin stimulates the tyrosine kinase activity of its receptor, resulting in the phosphorylation of its cytosolic substrate, insulin receptor substrate 1 (IRS-1).
