Abstract
Extralysosomal degradation of proteins is carried out by proteases complex (proteasomes), calcium dependent calpains, proteases of the rough endoplasmatic reticulum and proteases of the cellular membrane. It depends on a limited proteolysis and includes the main enzymatic proteins, hormones, growth factors and cytoskeletal proteins. Thus it plays an important regulatory role in the metabolism and formation of cellular structures.
