[Intracellular proteolysis]

This article is intended to give an overview of the most significant facts in the area of intracellular proteolysis. It begins with general considerations on the importance and nature of the intracellular proteolytic processes and examples are given of what takes place during both the extensive proteolysis and the limited cleavage of the cellular proteins. We have mentioned the intracellular proteases that have been identified and their established role since the knowledge of the proteases involved in important to understand the mechanisms of these processes.
