Abstract
The past few years have seen an explosion of knowledge on the subject of intracellular protein degradation. The view that lysosomes (or rather intra-lysosomal proteases) are primarily responsible for degrading intracellular proteins has now been discredited, and a large number of cytoplasmic proteolytic enzymes have been discovered. It now appears that lysosomes are mostly responsible for the degradation of cellular organelles, whereas most cytoplasmic proteins are degraded by soluble, cytoplasmic proteinases, proteases, and peptidases.1
