What is the official name of the GYS2 gene?
The official name of this gene is “glycogen synthase 2.”
GYS2 is the gene's official symbol. The GYS2 gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the GYS2 gene?
The GYS2 gene provides instructions for making an enzyme called liver glycogen synthase. Liver glycogen synthase is produced solely in liver cells, where it helps form the complex sugar glycogen by linking together molecules of the simple sugar glucose. Glucose that is taken in from food is stored in the body as glycogen, which is a major source of energy. Glycogen that is stored in the liver can be broken down rapidly when glucose is needed to maintain normal blood sugar levels between meals.
Does the GYS2 gene share characteristics with other genes?
The GYS2 gene belongs to a family of genes called glycosyltransferase group 1 domain containing (glycosyltransferase group 1 domain containing).
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.
