Furin

Enzyme found in humans

Furin is a protease, a proteolytic enzyme activated by substrate presentation that in humans and other animals is encoded by the FURIN gene. Some proteins are inactive when they are first synthesized, and must have sections removed in order to become active. Furin cleaves these sections and activates the proteins. It was named furin because it was in the upstream region of an oncogene known as FES. The gene was known as FUR and therefore the protein was named furin. Furin is also known as PACE. A member of family S8, furin is a subtilisin-like peptidase.
