The Role of the Proteolytic System of the Host Cell in Physiology and In the Early Stages of Viral Infection

Abstract

Understanding the regulatory function of proteolytic enzymes is of fundamental importance in the biological control of physiological processes. Dysfunction of proteinases and their regulation leads to viral, oncological, cardiovascular and other diseases. Proteolytic activation is most common among viruses of different taxonomic groups and concerns mainly glycoproteins, which perform the functions of adsorption and fusion.
