Background
Glucagon-like Peptide 1 Receptor (GLP-1R) is a member of the
Class B or secretin receptor-like family of G protein-coupled receptors (GPCRs)
(1, 2). Activation of GLP-1R signaling regulates secretion of insulin from pancreatic
beta -cells in a glucose-dependent manner (3). Human GLP-1R consists of an N-terminal,
extracellular domain (ECD) containing 6 conserved cysteine residues and a
transmembrane domain with seven membrane-spanning alpha-helices, characteristic
of GPCRs (2,4). The mature ECD of human GLP-1R shares 92% amino acid (aa) identity
with mouse GLP-1R. GLP-1R is expressed in pancreas, lung, heart,
kidney, hypothalamus, and stomach and it is a receptor for Glucagon-like
Peptide, a regulator of insulin secretion by pancreatic beta cells (1, 4, 5).
GLP1R agonists, including GLP-1, Boc5, and Cpd1, have been targeted for
research and used as type 2 diabetes treatments (5, 6). GLP1R is also expressed
in the brain where it is involved in the control of appetite (5).
