Cathepsin L

Cathepsin L is a type of enzyme found mainly in parts of our cells called lysosomes, where it helps break down proteins into smaller pieces. This process is essential for recycling cell components, regulating immune responses, and processing proteins that are involved in various body functions. Cathepsin L operates best in acidic conditions and plays a role in normal cell function, as well as in certain diseases like cancer and infections. Understanding this enzyme helps scientists develop treatments for some health conditions by targeting its activity.
