What is the official name of the PGK1 gene?
The official name of this gene is “phosphoglycerate kinase 1.”
PGK1 is the gene's official symbol. The PGK1 gene is also known by other names, listed below.

What is the normal function of the PGK1 gene?
The PGK1 gene provides instructions for making an enzyme called phosphoglycerate kinase. This enzyme is found in cells and tissues throughout the body, where it is involved in a critical energy-producing process known as glycolysis. During glycolysis, the simple sugar glucose is broken down to produce energy.
Phosphoglycerate kinase helps carry out a chemical reaction that converts a molecule called 1,3-diphosphoglycerate, which is produced during the breakdown of glucose, to another molecule called 3-phosphoglycerate. This reaction generates one molecule of adenosine triphosphate (ATP), which is the main energy source in cells.
Researchers suspect that phosphoglycerate kinase may have additional functions, although little is known about the other roles this enzyme may play in cells.
