Proprotein Convertase 4/PCSK4 Proteins and Enzymes

This family of serine proteases consists of furin and proprotein convertases encoded by PCSK genes. They are important in a variety of processes. Furin has an essential role in embryogenesis and homeostasis and is implicated in various pathologies such as cancer, neurodegenerative diseases and anthrax. Mutations in the PC1/PCSK1 gene are associated with obesity and impaired prohormone processing.
