CC   -!- FUNCTION: [Glucagon]: Plays a key role in glucose metabolism and
CC       homeostasis. Regulates blood glucose by increasing gluconeogenesis and
CC       decreasing glycolysis. A counterregulatory hormone of insulin, raises
CC       plasma glucose levels in response to insulin-induced hypoglycemia.
CC       Plays an important role in initiating and maintaining hyperglycemic
CC       conditions in diabetes. {ECO:0000250|UniProtKB:P55095}.
CC   -!- FUNCTION: [Glucagon-like peptide 1]: Potent stimulator of glucose-
CC       dependent insulin release. Also stimulates insulin release in response
CC       to IL6. Plays important roles on gastric motility and the suppression
CC       of plasma glucagon levels. May be involved in the suppression of
CC       satiety and stimulation of glucose disposal in peripheral tissues,
CC       independent of the actions of insulin. Has growth-promoting activities
CC       on intestinal epithelium. May also regulate the hypothalamic pituitary
CC       axis (HPA) via effects on LH, TSH, CRH, oxytocin, and vasopressin
CC       secretion. Increases islet mass through stimulation of islet neogenesis
CC       and pancreatic beta cell proliferation. Inhibits beta cell apoptosis.
CC       {ECO:0000250|UniProtKB:P55095}.
CC   -!- FUNCTION: [Glucagon-like peptide 2]: Stimulates intestinal growth and
CC       up-regulates villus height in the small intestine, concomitant with
CC       increased crypt cell proliferation and decreased enterocyte apoptosis.
CC       The gastrointestinal tract, from the stomach to the colon is the
CC       principal target for GLP-2 action. Plays a key role in nutrient
CC       homeostasis, enhancing nutrient assimilation through enhanced
CC       gastrointestinal function, as well as increasing nutrient disposal.
CC       Stimulates intestinal glucose transport and decreases mucosal
CC       permeability. {ECO:0000250|UniProtKB:P55095}.
CC   -!- FUNCTION: [Oxyntomodulin]: Significantly reduces food intake. Inhibits
CC       gastric emptying in humans. Suppression of gastric emptying may lead to
CC       increased gastric distension, which may contribute to satiety by
CC       causing a sensation of fullness. {ECO:0000250|UniProtKB:P55095}.
CC   -!- FUNCTION: [Glicentin]: May modulate gastric acid secretion and the
CC       gastro-pyloro-duodenal activity. May play an important role in
CC       intestinal mucosal growth in the early period of life.
CC       {ECO:0000250|UniProtKB:P55095}.
CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P01275}.
CC   -!- SUBCELLULAR LOCATION: [Glucagon-like peptide 1]: Secreted
CC       {ECO:0000250|UniProtKB:P01275}.
CC   -!- TISSUE SPECIFICITY: Glucagon is secreted in the A cells of the islets
CC       of Langerhans. GLP-1, GLP-2, oxyntomodulin and glicentin are secreted
CC       from enteroendocrine cells throughout the gastrointestinal tract.
CC   -!- INDUCTION: Glucagon release is stimulated by hypoglycemia and inhibited
CC       by hyperglycemia, insulin, and somatostatin. GLP-1 and GLP-2 are
CC       induced in response to nutrient ingestion (By similarity).
CC       {ECO:0000250}.
CC   -!- PTM: Proglucagon is post-translationally processed in a tissue-specific
CC       manner in pancreatic A cells and intestinal L cells. In pancreatic A
CC       cells, the major bioactive hormone is glucagon cleaved by PCSK2/PC2. In
CC       the intestinal L cells PCSK1/PC1 liberates GLP-1, GLP-2, glicentin and
CC       oxyntomodulin. GLP-1 is further N-terminally truncated by post-
CC       translational processing in the intestinal L cells resulting in GLP-
CC       1(7-37) GLP-1-(7-36)amide. The C-terminal amidation is neither
CC       important for the metabolism of GLP-1 nor for its effects on the
CC       endocrine pancreas (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the glucagon family. {ECO:0000305}.
