Researchers uncover the role of glutaminase 2 in glucose homeostasis

Glutaminase 2 (GLS2) is a master regulator of glutaminolysis. GLS2 converts glutamine to glutamate, thereby playing a role in cellular energy production. GLS2 is abundant in the liver, and is also found in pancreatic β-cells. However, the role of GLS2 in pancreatic islets – in which both ɑ- and β- cells are present – associated with glucose metabolism is currently unknown.
