Fission yeast 26S proteasome mutants are multi-drug resistant due to stabilization of the pap1 transcription factor [PDF]

open access: yes, 2012
Here we report the result of a genetic screen for mutants resistant to the microtubule poison methyl benzimidazol-2-yl carbamate (MBC) that were also temperature sensitive for growth.

Proteasome inhibition-enhanced fracture repair is associated with increased mesenchymal progenitor cells in mice.

open access: yesPLoS ONE, 2022
The ubiquitin/proteasome system controls the stability of Runx2 and JunB, proteins essential for differentiation of mesenchymal progenitor/stem cells (MPCs) to osteoblasts.

Fluorescence-based proteasome activity profiling [PDF]

open access: yes, 2012
With the proteasome emerging as a therapeutic target for cancer treatment, accurate tools for monitoring proteasome (inhibitor) activity are in demand.

Assembly of the Drosophila 26 S proteasome is accompanied by extensive subunit rearrangements [PDF]

open access: yes, 2002
The subunit contacts in the regulatory complex of the Drosophila 26 S proteasome were studied through the cross-linking of closely spaced subunits of the complex, and analysis of the cross-linking pattern in an immunoblot assay with the use of subunit ...

Intracellular Dynamics of the Ubiquitin-Proteasome-System [version 2; referees: 3 approved]

open access: yesF1000Research, 2015
The ubiquitin-proteasome system is the major degradation pathway for short-lived proteins in eukaryotic cells. Targets of the ubiquitin-proteasome-system are proteins regulating a broad range of cellular processes including cell cycle progression, gene ...

The ubiquitin proteasome system in neuropathology [PDF]

open access: yesActa Neuropathologica, 2009
The ubiquitin proteasome system (UPS) orchestrates the turnover of innumerable cellular proteins. In the process of ubiquitination the small protein ubiquitin is attached to a target protein by a peptide bond. The ubiquitinated target protein is subsequently shuttled to a protease complex known as the 26S proteasome and subjected to degradative ...

The molecular basis of CRL4 ubiquitin ligase architecture, targeting and regulation [PDF]

open access: yes, 2013
Members of the CUL4-RBX1-DDB1 (CRL4) E3 ubiquitin ligase family regulate multiple cellular processes including development, transcription, and DNA repair.

Up-regulation of ubiquitin–proteasome activity upon loss of NatA-dependent N-terminal acetylation

open access: yesLife Science Alliance, 2022
Inactivation of N-terminal acetyltransferase A is found to alter Rpn4 as well as E3 ligase abundance, causing up-regulation of Ubiquitin–proteasome activity.

Regulation of SCF Ubiquitin Ligases by Jab1/Csn5 and the Cop9 Signalosome [PDF]

open access: yes, 2006
SCF ubiquitin ligases regulate the ubiquitin-dependent proteolysis of a myriad of substrate proteins, including p27, Cyclin E, and IkBa. To further gain insight into SCF regulation and function, we purified SCF from mammalian cells and found the Cop9 ...
