What is the official name of the NCF2 gene?
The official name of this gene is “neutrophil cytosolic factor 2.”
NCF2 is the gene's official symbol. The NCF2 gene is also known by other names, listed below.

What is the normal function of the NCF2 gene?
The NCF2 gene provides instructions for making a protein called neutrophil cytosolic factor 2 (also known as p67-phox). This protein is one part (subunit) of a group of proteins that forms an enzyme complex called NADPH oxidase, which plays an essential role in the immune system. Specifically, NADPH oxidase is primarily active in immune system cells called phagocytes. These cells catch and destroy foreign invaders such as bacteria and fungi. NADPH oxidase is also thought to regulate the activity of immune cells called neutrophils. These cells play a role in adjusting the inflammatory response to optimize healing and reduce injury to the body.
The presence of foreign invaders stimulates phagocytes and triggers the assembly of NADPH oxidase. This enzyme participates in a chemical reaction that converts oxygen to a toxic molecule called superoxide. Superoxide is used to generate several other compounds, including hydrogen peroxide (a strong disinfectant) and hypochlorous acid (the active ingredient in bleach). These highly reactive, toxic substances are known as reactive oxygen species. Phagocytes use these substances to kill foreign invaders, preventing them from reproducing in the body and causing illness.
Does the NCF2 gene share characteristics with other genes?
The NCF2 gene belongs to a family of genes called TTC (tetratricopeptide (TTC) repeat 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.
How are changes in the NCF2 gene related to health conditions?
Genetics Home Reference provides information about systemic lupus erythematosus, which is also associated with changes in the NCF2 gene.
Where is the NCF2 gene located?
Cytogenetic Location: 1q25
Molecular Location on chromosome 1: base pairs 183,555,561 to 183,590,920
The NCF2 gene is located on the long (q) arm of chromosome 1 at position 25.
More precisely, the NCF2 gene is located from base pair 183,555,561 to base pair 183,590,920 on chromosome 1.
