CC   -!- FUNCTION: Gastrin stimulates the stomach mucosa to produce and secrete
CC       hydrochloric acid and the pancreas to secrete its digestive enzymes. It
CC       also stimulates smooth muscle contraction and increases blood
CC       circulation and water secretion in the stomach and intestine.
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- PTM: Sulfation enhances proteolytic processing, and blocks peptide
CC       degradation. Levels of sulfation differ between proteolytically-cleaved
CC       gastrins and between tissues (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the gastrin/cholecystokinin family.
CC       {ECO:0000305}.
