What are the functions of proteases?

Posted May 19, 2023


Proteases play a vital role in several essential biological processes including: 

  • Activating or speeding up the processes of cell division, immune support, blood coagulation, bone formation, and maturation of prohormones
  • Digesting dietary proteins, which facilitates the absorption of amino acids
  • Modulating protein-protein interactions
  • Facilitating protein recycling and transport across membranes
  • Generating, amplifying and transducing molecular signals
  • Creating new bioactive molecules
  • Processing of cellular information
  • Activating or speeding up cell growth, division, migration, and apoptosis
  • Speeding up wound healing
  • Regulating the process of inflammation, metastasis, and tumor growth
