neutrophil cytosolic factor 1

آخر تحديث 17 أبريل 2023

The NCF1 gene provides instructions for making a protein called neutrophil cytosolic factor 1 (also known as p47-phox). This protein is one part (subunit) of a group of proteins that forms an enzyme complex called NADPH oxidase (NOX), which plays an essential role in the immune system. NOX is primarily active in immune system cells called phagocytes. These cells catch and destroy foreign invaders such as bacteria and fungi. NOX 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 NCF1 gene provides instructions for making a protein called neutrophil cytosolic factor 1 (also known as p47-phox). This protein is one part (subunit) of a group of proteins that forms an enzyme complex called NADPH oxidase (NOX), which plays an essential role in the immune system. NOX is primarily active in immune system cells called phagocytes. These cells catch and destroy foreign invaders such as bacteria and fungi. NOX 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 NOX. 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 (ROS). Phagocytes use these substances to kill foreign invaders, preventing them from reproducing in the body and causing illness.

NOX plays a role in other cell types as well, such as blood vessel cells. Abnormal blood flow in blood vessels can trigger these cells to make more NOX, which stimulates the production of ROS. These compounds can influence blood pressure and other biological processes.
