Background Information
Background
Glucagon is a protein cleaved from a precursor protein encoded by the GCG gene. The distinct peptides formed from this precursor include Glucagon, Glucagon-Like Peptide 1 (GLP-1), Glucagon-Like Peptide 2 (GLP-2), and oxyntomodulin. Glucagon is essential in maintaining blood glucose homeostasis and therefore has a key role in Type 1 and Type 2 diabetes.
What is the molecular weight of Glucagon?
21 kDa. Glucagon is composed of 180 amino acids and is a ligand for a specific G-protein coupled receptor (GPCR).
Where is it expressed?
Glucagon is a hormone secreted by the pancreas, in the α cells of the islets of Langerhans (PMID: 18880761). GLP-1, GLP-2, and oxyntomodulin are secreted by gut endocrine cells of the GI tract and also by selected neurons in the brain. These secreted proteins are transported to the target organ in plasma.
What is the function of glucagon?
The regulation of blood glucose levels is controlled by a balance of the hormones INS and glucagon in a negative feedback loop. A drop in blood glucose, or hypoglycemia, stimulates the release of glucagon. This initiates a cascade of signals, ultimately causing the conversion of stored glycogen into free glucose in a process called glycogenolysis, which takes place in liver and muscle cells. Glucagon can also stimulate gluconeogenesis in the liver, the process of forming glucose from non-carbohydrate sources such as amino acids (PMID: 13477815).
What diseases are associated with glucagon?
Glucagon is key in homeostasis of blood glucose and maintaining the balance between hyperglycaemia and hypoglycemia. It is therefore important in the study of Type 1 and Type 2 diabetes mellitus, where dysfunction of the pancreatic cells leads to a deregulation of blood glucose levels (PMID: 19326096). In both forms of the disease, glucagon secretion is impaired, from too much being secreted during hyperglycaemia, to too little being released to normalize hypoglycemia (PMID: 18197838).
