What is the official name of the PDP1 gene?
The official name of this gene is “pyruvate dehydrogenase phosphatase catalytic subunit 1.”
PDP1 is the gene's official symbol. The PDP1 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 PDP1 gene?
The PDP1 gene provides instructions for making a protein called pyruvate dehydrogenase phosphatase 1, which is part of a large group of proteins called the pyruvate dehydrogenase complex. The pyruvate dehydrogenase phosphatase 1 protein turns on (activates) the complex by removing a phosphate group (a cluster of oxygen and phosphorus atoms) from the complex.
The pyruvate dehydrogenase complex plays an important role in the pathways that convert the energy from food into a form that cells can use. This enzyme converts a molecule called pyruvate, which is formed from the breakdown of carbohydrates, into another molecule called acetyl-CoA. This conversion is essential to begin the series of chemical reactions that produces adenosine triphosphate (ATP), the cell's main energy source.
Does the PDP1 gene share characteristics with other genes?
The PDP1 gene belongs to a family of genes called serine/threonine phosphatases (serine/threonine phosphatases).
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.
