Independence of Glucagon Receptors and Glucagon Inactivation in Liver Cell Membranes
Nature New Biology, 1972THERE is increasing evidence that receptors for polypeptide hormones are localized on the cell membrane. Hormone-receptor interactions have been studied primarily by measuring the bmding of 125I-labelled hormones to intact1 or broken-cell preparations2–6.

Cloning and Expression of a Human Glucagon Receptor
Biochemical and Biophysical Research Communications, 1994A human glucagon receptor has been cloned from human liver tissue. The 1578-bp cDNA clone encodes a protein of 477 amino acids with 82% identity to the rat glucagon receptor. The predicted secondary structure and homology to known proteins places this receptor within the superfamily of seven transmembrane domain G protein coupled receptors ...

Regulation of Rat Glucagon Receptor Expression
Biochemical and Biophysical Research Communications, 1994This report describes the isolation of a cDNA for the rat glucagon receptor by using the glucagon-like peptide 1 receptor cDNA as a probe. Northern blot analysis using the cDNA clone showed that the message encoding the receptor is approximately 2.3 kb in size and is expressed only in liver and kidney among seven tissues tested.

Identification of Glucagon Receptors in Rat Retina
Journal of Neurochemistry, 1990Abstract:In this study, we characterize the glucagon receptors on rat retinal particulate preparations. The specific binding of 125I‐glucagon was saturable and reversible. Apparent equilibrium conditions were established within 30–45 min. Analysis of binding data is compatible with the existence of two classes of binding sites: a high‐affinity class ...

Annales de biologie clinique, 1977
The lecturer recalls the discovery of glucagon receptors in liver cell membranes, the role of the adenylate cyclase-AMPc system, until recent attempts at purification and isolation of this receptor. He then reviews successively, the problems of estimation, specificity of the interaction, the effects of purine and pyrimidine nucleotides on glucagon ...

Biaryl amide glucagon receptor antagonists
Bioorganic & Medicinal Chemistry Letters, 2004Biaryl amides derived from a reported series of ureas 1 were evaluated and found to be potent human glucagon receptor antagonists. The benzofuran analogue 6i was administered in Sprague-Dawley rats and blocked the effects of an exogenous glucagon challenge.

Glucagon receptor signaling in metabolic diseases
Peptides, 2018Glucagon is a peptide hormone secreted from the pancreatic alpha cells in response to hypoglycemia but in some patients with type 2 diabetes a paradoxical hypersecretion results from the intake of glucose. In rodent, antagonizing the actions of glucagon have been shown to be effective for lowering blood glucose levels and this has recently have been ...

Evolution of receptors for peptides similar to glucagon
General and Comparative Endocrinology, 2014The genes encoding the peptide precursors for glucagon (GCG), glucose-dependent insulinotropic peptide (GIP), and ortholog of exendin belong to the same family as shown by sequence similarity. The peptides similar to glucagon encoded by these genes signal through a closely related subfamily of G-protein coupled receptors. A total of five types of genes
