Sigma Aldrich Fine Chemicals Biosciences Proteasome 20S Activity As

Supplier:  Sigma Aldrich Fine Chemicals Biosciences MAK1721KT

Protein degradation occurs most commonly through two major mechanisms lysosomal degradation and proteasome mediated degradation. Lysosomal degradation occurs through proteolytic enzyme activity and is fairly non-specific. Proteasomal degradation is targeted for a specific protein through the ubiquitination of the target protein. The target protein is typically poly-ubiquitinated and activates the 26S proteasome toward proteolysis. The proteasome 26S is the most common form of the proteasome and is an ATP-dependent proteolytic complex which contains one 20S (700-kDa) core particle structure and two 19S (700-kDa) regulatory caps.The proteasome is responsible for the recycling of proteins and maintenance of the balance of protein synthesis and degradation. The proteasome is involved with apoptosis DNA repair endocytosis and cell cycle and has been implicated in disease states such as certain types of cancer diabetes mellitus and Alzheimer disease among others making it the target f
