Engineering novel peptide agonists of the glucagon-like peptide-1 receptor
Abstract/Contents
- Abstract
- Understanding the molecular operations of G-protein coupled receptors and their ligands is a central goal in the project of understanding human physiology and altering it with pharmacological agents to improve human health. Receptors in GPCR class B have pharmacological and structural features that are distinct among GPCRs because they are evolutionarily adapted to bind and respond to short, alpha-helical peptide ligands instead of small molecule ligands. The glucagon-like peptide-1 receptor (GLP-1R) is a class B G-protein coupled receptor and diabetes drug target expressed mainly in the pancreatic β-cells that, when activated by its agonist GLP-1 after a meal, triggers insulin secretion and β-cell survival and proliferation. The best-studied agonist peptides, GLP-1 and exendin-4, share sequence homology at their N-terminal region; however, modifications to this region that can be tolerated are not fully understood. In this work, I have used combinatorial peptide screening coupled with chemical exploration with non-canonical amino acid substitutions to find novel and highly active GLP-1R agonists with altered N-terminal composition and to explore the principles that govern peptide activity.
