Glucagon and related peptide receptors are a group of G-protein-coupled receptors that are currently classified into six subtypes; Glucagon, Glucagon-Like Peptide 1 (GLP-1), GLP-2, Secretin, Growth Hormone Releasing Hormone (GHRH) and Gastric Inhibitory Peptide (GIP) based on their pharmacology. This family of class II G-protein-coupled receptors serve multiple biological functions including the regulation of nutrient homeostasis through effects on islet hormone secretion, gastrointestinal motility and cell proliferation.
Tocris offers the following scientific literature for Glucagon and Related Receptors to showcase our products. We invite you to request* or download your copy today!
*Please note that Tocris will only send literature to established scientific business / institute addresses.
Written by Sonia Tucci, Lynsay Kobelis and Tim Kirkham, this review provides a synopsis of the increasing number of peptides that have been implicated in appetite regulation and energy homeostasis; putative roles of the major peptides are outlined and compounds available from Tocris are listed.
