The ubiquitin–proteasome system (UPS) and autophagy are two distinct and interacting proteolytic systems. They play critical roles in cell survival under normal conditions and during stress.

Inhibitory Effect of b-AP15 on the 20S Proteasome
The 26S proteasome is a cellular proteolytic complex containing 19S regulatory particles and the 20S core proteasome. It was reported that the small molecule b-AP15 targets the proteasome by inhibiting deubiquitination of the 19S regulatory particles of

Inhibition on Proteasome β1 Subunit Might Contribute to the Anti-Cancer Effects of Fangchinoline in Human Prostate Cancer Cells. [PDF]
Fangchinoline is a bisbenzylisoquinoline alkaloid isolated from Radix Stephaniae tetrandrae S. Moore. Fangchinoline and its structure analogue, tetrandrine, exhibited direct binding affinity with recombinant human proteasome β1 subunit and also inhibited

Deletion of proteasomal subunit S5a/Rpn10/p54 causes lethality, multiple mitotic defects and overexpression of proteasomal genes in Drosophila melanogaster [PDF]
The regulatory complex of the 26S proteasome is responsible for the selective recognition and binding of multiubiquitinated proteins. It was earlier shown that the subunit S5a/Rpn10/p54 of the regulatory complex is the only cellular protein capable of ...

Proteasome inhibitors have a 20 year history in cancer therapy. The first proteasome inhibitor, bortezomib (Velcade, PS-341), a break-through multiple myeloma treatment, moved rapidly through development from bench in 1994 to first approval in 2003. Bortezomib is a reversible boronic acid inhibitor of the chymotrypsin-like activity of the proteasome ...

FoxO1 Is a Novel Regulator of 20S Proteasome Subunits Expression and Activity
Proteostasis collapses during aging resulting, among other things, in the accumulation of damaged and aggregated proteins. The proteasome is the main cellular proteolytic system and plays a fundamental role in the maintenance of protein homeostasis.

Radiosensitization of noradrenaline transporter-expressing tumour cells by proteasome inhibitors and the role of reactive oxygen species [PDF]
Background The radiopharmaceutical 131I-metaiodobenzylguanidine (131I-MIBG) is used for the targeted radiotherapy of noradrenaline transporter (NAT)-expressing neuroblastoma.

Rising interest in the mechanism and function of the proteasomes and the ubiquitin system revealed that it is hard to find any aspect of the cellular metabolic network that is not directly or indirectly affected by the degradation system. This includes the cell cycle, the "quality control" of newly synthesized proteins (ERAD), transcription factor ...

Proteasome beta-4 subunit contributes to the development of melanoma and is regulated by miR-148b
The proteasome beta-4 subunit is required for the assembly of 20S proteasome complex, forming a pivotal component for the ubiquitin–proteasome system. Emerging evidence indicates that proteasome beta-4 subunit may be involved in underlying progression ...

Proteasome inhibition by new dual warhead containing peptido vinyl sulfonyl fluorides [PDF]
The success of inhibition of the proteasome by formation of covalent bonds is a major victory over the long held-view that this would lead to binding the wrong targets and undoubtedly lead to toxicity.
