What is the official name of the ISCU gene?
The official name of this gene is “iron-sulfur cluster assembly enzyme.”
ISCU is the gene's official symbol. The ISCU gene is also known by other names, listed below.

What is the normal function of the ISCU gene?
The ISCU gene provides instructions for making a protein called the iron-sulfur cluster assembly enzyme. As its name suggests, this enzyme is involved in the formation of clusters of iron and sulfur atoms (Fe-S clusters). Specifically, the enzyme acts as a platform, or scaffold, for the assembly of these clusters. Fe-S clusters are critical for the function of many different proteins, including those needed for DNA repair and the regulation of iron levels. Proteins containing Fe-S clusters are also necessary for energy production within mitochondria, which are the cell structures that convert the energy from food into a form that cells can use.
How are changes in the ISCU gene related to health conditions?
Where is the ISCU gene located?
