Furin

Furin is a type of enzyme found in our bodies, functioning like a molecular scissors. It helps process and activate proteins by cutting them at specific spots, which is essential for their proper function. Furin is involved in various biological processes, including cell growth, immune response, and the development of certain tissues. Some viruses, like COVID-19, hijack furin to help their proteins become infectious, aiding their entry into human cells. Overall, furin plays a critical role in maintaining healthy cell activity and can influence disease progression when its activity is altered.
