General Information

ID: hor006383
Uniprot ID: P05110
Protein name: Glicentin
Gene name: GCG
Organism: Cavia porcellus (Guinea pig)
Family: Glucagon family
Source: Animal
Expression: Glucagon release is stimulated by hypoglycemia and inhibited by hyperglycemia, insulin, and somatostatin. GLP-1 and GLP-2 are induced in response to nutrient ingestion (By similarity).
Disease: NA
Comments: NA
