Proteasomes and immunoproteasomes.
Rivista di biologia, 2011In eukaryotic cells, the protein degradation is a highly regulated and selective process. Membrane-associated or extracellular proteins are degraded in lysosomes, whereas intracellular protein dismantling is primarily non-lysosomal, being realized by complex, not-membrane enclosed and energy-dependent effectors, the proteasomes, localized in both ...

In this report, we examine the involvement of the ubiquitin-proteasome pathway during fusion and differentiation of myoblast primary cell cultures. Up-regulation of proteasome was observed at the maximum fusion rate and was preceded by an increase of unidentified ubiquitin-conjugates.

Yeast 26S proteasome bound to ubiquitinated substrate (1D* motor state)
, 2018The 26S proteasome is the primary eukaryotic degradation machine and thus is critically involved in numerous cellular processes. The heterohexameric adenosine triphosphatase (ATPase) motor of the proteasome unfolds and translocates targeted protein ...

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 ...

Proteasomes and proteasome inhibition in the central nervous system
Free Radical Biology and Medicine, 2001Although the proteasome is responsible for the majority of intracellular protein degradation, and has been demonstrated to play a pivotal role in a diverse array of cellular activities, the role of the proteasome in the central nervous system is only beginning to be elucidated.

In May 2003, the US Food and Drug Administration (FDA) granted accelerated approval for the use of the first-in-class proteasome inhibitor bortezomib as a third-line therapy in multiple myeloma, and the European Union followed suit a year later. Bortezomib has subsequently been approved for multiple myeloma as a second-line treatment on its own and as ...

Anti‐20S proteasome autoantibodies inhibit proteasome stimulation by proteasome activator PA28
Arthritis & Rheumatism, 2006AbstractObjectiveThe ubiquitin‐proteasome system plays a central role in cellular homeostasis as well as in regulation of the inflammatory and stress responses. However, the occurrence of autoantibodies against 20S proteasome has, to date, been considered to be a nonspecific epiphenomenon in patients with autoimmune disorders. This study was undertaken

In contrast to our detailed knowledge of prokaryotic proteasomes, we have only a limited understanding of the prokaryotic regulators and their functional interaction with the proteasome. Most probably, we will soon learn more about the molecular structure and the mechanism of action of the prokaryotic regulators.

The ubiquitin-proteasome pathway is responsible for the regular turnover of a wide variety of proteins and is a critical regulator of many cellular processes. Although this pathway is abundant and ubiquitous, it is also discriminating. This specificity is achieved because there are multiple levels of regulation at work in the pathway.

Cancer is one of the most frightful diseases mostly resulting in mortality; it has recently become more possible to overcome with the help of new therapies. In this direction, carcinogenesis is defined as a complicated process that can include several different factors that contribute to its progress. Proteasome is implicated in cancer studies as it is
