What is glycogen synthase?

Glycogen synthase is an enzyme responsible for converting glucose into glycogen, a form of stored energy in the body. It plays a key role in regulating blood sugar levels and energy storage in the liver and muscles.

There are two main isoforms of glycogen synthase, known as glycogen synthase 1 (GYS1) and glycogen synthase 2 (GYS2), which are expressed in different tissues in the body.

Glycogen synthase is regulated by several factors, including insulin, glucose levels, and other signaling molecules. Insulin activates glycogen synthase, promoting the storage of glucose as glycogen, while other factors such as epinephrine can inhibit its activity.

Mutations in the gene encoding glycogen synthase have been associated with glycogen storage diseases, a group of genetic disorders characterized by abnormalities in glycogen metabolism.

Overall, glycogen synthase is a critical enzyme in the regulation of energy metabolism and plays a crucial role in maintaining proper glucose levels in the body.
