Agonism and Antagonism at the Insulin Receptor
PLoS ONE, 2012 Insulin can trigger metabolic as well as mitogenic effects, the latter being pharmaceutically undesirable. An understanding of the structure/function relationships between insulin receptor (IR) binding and mitogenic/metabolic signalling would greatly facilitate the preclinical development of new insulin analogues.

MARCH1 regulates insulin sensitivity by controlling cell surface insulin receptor levels
Nature Communications, 2016 Insulin receptor levels at the cell surface are reduced in insulin resistance, for reasons that are not fully understood. Here, the authors identify the E3 ubiquitin ligase MARCH1 as a direct regulator of basal insulin receptor surface levels and ...

A high-fructose diet induces changes in pp185 phosphorylation in muscle and liver of rats
Brazilian Journal of Medical and Biological Research, 2000 Insulin stimulates the tyrosine kinase activity of its receptor resulting in the tyrosine phosphorylation of pp185, which contains insulin receptor substrates IRS-1 and IRS-2. These early steps in insulin action are essential for the metabolic effects of

The insulin superfamily of growth-promoting proteins [PDF]
arXiv, 2007 Recently, structural analysis of the human transferrin and growth hormone (GH) amino acid sequences has unravelled that they harbor a motif identical to a pattern found in viral oncoproteins known to bind the primarily nuclear tumor suppressor retinoblastoma protein (RB).

Modeling the distribution of insulin in pancreas [PDF]
arXivMaintenance of adequate physical and functional pancreatic $\beta$-cell mass is critical for the prevention or delay of diabetes mellitus. It is well established that insulin potently activates mitogenic and anti-apoptotic signaling cascades in cultured $\beta$-cells.

Antiproliferative MCR peptides block physical interaction of insulin with retinoblastoma protein (RB) in human lung cancer cells [PDF]
arXiv, 2007 Fifteen years ago, a structural analysis of the hormone insulin and the retinoblastoma tumor suppressor protein (RB) revealed that they may physically interact with one another. Subsequently, an RB peptide corresponding to the proposed RB binding site for insulin was found to recognize full-length insulin in vitro.

New Twist on Neuronal Insulin Receptor Signaling in Health, Disease, and Therapeutics
Journal of Pharmacological Sciences, 2005 Long after the pioneering studies documenting the existence of insulin (year 1967) and insulin receptor (year 1978) in brain, the last decade has witnessed extraordinary progress in the understanding of brain region-specific multiple roles of insulin ...

Insulin and insulin receptor abnormality.
Nihon Naika Gakkai Zasshi, 1993 インスリンあるいはインスリン受容体の異常が糖尿病者で見い出された.インスリン受容体に結合しえない異常インスリンやプロインスリンが産生されるインスリン遺伝子の異常,細胞表面のインスリン受容体の数や機能が減少するインスリン受容体遺伝子の異常あるいはインスリン受容体に対する自己抗体の存在が報告されている.いずれも高インスリン血症の存在が診断への手掛りとなるが,インスリンの異常ではインスリン抵抗性は存在しないがインスリン受容体の異常では存在する点が最大の鑑別点となる.インスリン遺伝子あるいはインスリン受容体遺伝子の異常が見い出された家系について検討すると,糖尿病の発症年齢,重症度は均一でなく,その発症には他の遺伝子異常あるいは環境要因の関与も推定され,糖尿病の発症にはいくつかの因子が関与していると考えられた.

Structure and dynamics of dynorphin peptide and its receptor [PDF]
arXiv, 2019 Dynorphin is a neuropeptide involved in pain, addiction and mood regulation. It exerts its activity by binding to the kappa opioid receptor (KOP) which belongs to the large family of G-protein coupled receptors. The dynorphin peptide was discovered in 1975, while its receptor was cloned in 1993.
