Dss1 Is a 26S Proteasome Ubiquitin Receptor [PDF]
The ubiquitin-proteasome system is the major pathway for protein degradation in eukaryotic cells. Proteins to be degraded are conjugated to ubiquitin chains that act as recognition signals for the 26S proteasome. The proteasome subunits Rpn10 and Rpn13 are known to bind ubiquitin, but genetic and biochemical data suggest the existence of at least one ...

Degradation of Intrinsically Disordered Proteins by the NADH 26S Proteasome
The 26S proteasome is the endpoint of the ubiquitin- and ATP-dependent degradation pathway. Over the years, ATP was regarded as completely essential for 26S proteasome function due to its role in ubiquitin-signaling, substrate unfolding and ensuring its ...

Background: Type I interferons (IFN-α/β) have broad and potent immunoregulatory and antiproliferative activities. However, it is still known whether the dietary flavonoids exhibit their antiviral and anticancer properties by modulating the function of ...

Phosphorylation of ATPase subunits of the 26S proteasome [PDF]
The 26S proteasome complex plays a major role in the non‐lysosomal degradation of intracellular proteins. Purified 26S proteasomes give a pattern of more than 40 spots on 2D‐PAGE gels. The positions of subunits have been identified by mass spectrometry of tryptic peptides and by immunoblotting with subunit‐specific antipeptide antibodies.

A kinetic model for USP14 regulated substrate degradation in 26S proteasome. [PDF]
Despite high-resolution structural studies on the USP14-proteasome-substrate complexes, time-resolved cryo-electron microscopy (cryo-EM) results on USP14-regulated allostery of the 26S proteasome are still very limited and a quantitative understanding of

UBLCP1 is a 26S proteasome phosphatase that regulates nuclear proteasome activity [PDF]
Protein degradation by the 26S proteasome is a fundamental process involved in a broad range of cellular activities, yet how proteasome activity is regulated remains poorly understood. We report here that ubiquitin-like domain-containing C-terminal domain phosphatase 1 (UBLCP1) is a 26S proteasome phosphatase that regulates nuclear proteasome activity.

SnRK2.6-mediated phosphorylation stabilizes proteasome regulator 1 (PTRE1) to enhance 26S proteasome activity and coordinate ABA signaling in Arabidopsis [PDF]
Abscisic acid (ABA) regulates diverse aspects of plant growth, particularly adaptive responses to abiotic stress. Although the ubiquitin–proteasome system is recognized as a pivotal pathway for degrading key components of ABA signaling, the mechanisms ...

Mechanisms of substrate recognition by the 26S proteasome. [PDF]
The majority of regulated protein degradation in eukaryotes is accomplished by the 26S proteasome, the large proteolytic complex responsible for removing regulatory proteins and damaged proteins. Proteins are targeted to the proteasome by ubiquitination, and degradation is initiated at a disordered region within the protein.
