Uniprot ID: P01274
Protein name: Glicentin-related polypeptide
Gene name: GCG
Organism: Sus scrofa (Pig)
Family: Glucagon family

Activity

Function: [Glucagon]: Plays a key role in glucose metabolism and homeostasis. Regulates blood glucose by increasing gluconeogenesis and decreasing glycolysis. A counterregulatory hormone of insulin, raises plasma glucose levels in response to insulin-induced hypogl
Mechanism: GLP-2 does not have cleavage on a pair of basic residues at C-terminus as in other mammals.
