What is the official name of the CTSF gene?
The official name of this gene is “cathepsin F.”
CTSF is the gene's official symbol. The CTSF 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 CTSF gene?
The CTSF gene provides instructions for making an enzyme called cathepsin F. Cathepsin F is one of a family of cathepsin proteins that act as proteases, which modify proteins by cutting them apart. Cathepsin F is found in many types of cells and is active in lysosomes, which are compartments within cells that digest and recycle different types of molecules. By cutting proteins apart, cathepsin F can break proteins down, turn on (activate) proteins, and regulate self-destruction of the cell (apoptosis).
Does the CTSF gene share characteristics with other genes?
The CTSF gene belongs to a family of genes called CTS (cathepsins).
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.
