What is the official name of the ANG gene?
The official name of this gene is “angiogenin, ribonuclease, RNase A family, 5.”
ANG is the gene's official symbol. The ANG gene is also known by other names, listed below.

What is the normal function of the ANG gene?
The ANG gene provides instructions for making a protein called angiogenin. This protein promotes the formation of new blood vessels from pre-existing blood vessels through a process called angiogenesis. In this process, angiogenin helps stimulate the growth and division of endothelial cells, which line the inside surface of blood vessels, to form new blood vessels. Angiogenesis is important for restoring blood flow after an injury. Angiogenin may also be involved in other steps of angiogenesis, such as helping to break down the tissue that surrounds existing blood vessels to allow room for the growth of new blood vessels.
Angiogenin is found in a variety of cells throughout the body and circulates in the bloodstream. When angiogenin attaches (binds) to receptors on the surface of endothelial cells, it triggers a series of reactions that bring angiogenin inside the cell. Once inside endothelial cells, angiogenin moves to the nucleus where it plays a role in regulating protein production. To stimulate the production of proteins, angiogenin triggers the production of ribosomal RNA (rRNA), a chemical cousin of DNA. Ribosomal RNA is required for assembling protein building blocks (amino acids) into functioning proteins. Angiogenin triggers the production of rRNA when there is an increased demand for proteins, such as for the growth and division of endothelial cells. When proteins are not needed, angiogenin breaks down a form of RNA called transfer RNA (tRNA), which, along with rRNA, is needed for assembling amino acids into full-length, functioning proteins.
Research findings suggest that angiogenin also has antimicrobial properties, which means it can help fight infections caused by bacteria and fungi.
Does the ANG gene share characteristics with other genes?
The ANG gene belongs to a family of genes called RNASE (ribonucleases, RNase A).
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.
