GLP-1
Also known as: glucagon-like peptide 1, GLP-1 7-36 amide
GLP-1, or glucagon like peptide 1, is a peptide cut from the pro glucagon precursor and listed here in the metabolic category for research information only. It is studied mainly in relation to glucose control, insulin release, and movement and function in the gut. Work on its receptor has also broadened into research areas that include the brain, the heart, the kidneys, and behavior.

Overview
Gastrointestinal peptide hormone involved in glucose homeostasis
Glucagon-like peptide-1 (GLP-1) is a 30- or 31-amino-acid-long peptide hormone deriving from tissue-specific posttranslational processing of the proglucagon peptide. It is produced and secreted by intestinal enteroendocrine L-cells and certain neurons within the nucleus of the solitary tract in the brainstem upon food consumption. The initial product GLP-1 (1–37) is susceptible to amidation and proteolytic cleavage, which gives rise to the two truncated and equipotent biologically active forms, GLP-1 (7–36) amide and GLP-1 (7–37). Active GLP-1 protein secondary structure includes two α-helices from amino acid position 13–20 and 24–35 separated by a linker region.
Mechanism of Action
Reference records characterize GLP-1 as strongly promoting insulin release when glucose is present, while also being linked to reduced glucagon in plasma and to changes in gastric motility. It is discussed in connection with growth and survival of pancreatic beta cells, growth of the intestinal lining, and signals that relate to appetite and eating. These effects are examined through the GLP-1 receptor, which is the central focus of the recent studies summarized here.
Research History
GLP-1 research developed from studies of how pro glucagon is processed and how gut hormones respond after nutrients arrive. Mapping its human sequence and showing that it promotes insulin release in a way that depends on glucose helped shape a large follow up literature. Recent publications include database analyses, cohort work, reviews, and pooled analyses that look at GLP-1 receptor signaling in many different groups and settings.
