Molecular basis of Lys11-polyubiquitin specificity in the deubiquitinase Cezanne [PDF]

open access: yes, 2016
The post-translational modification of proteins with polyubiquitin regulates virtually all aspects of cell biology. Eight distinct chain linkage types in polyubiquitin co-exist and are independently regulated in cells.

A plague of deubiquitination [PDF]

open access: yesThe Journal of Experimental Medicine, 2005
Plague bacteria inject infected host cells with a ubiquitin-chopping enzyme, according to Zhou and colleagues in a study on [page 1327][1]. The group shows that the virulence factor YopJ operates as a deubiquitinase to shut down multiple signaling pathways that would otherwise help trigger ...

Exercise serum promotes DNA damage repair and remodels gene expression in colon cancer cells

open access: yesInternational Journal of Cancer, Volume 158, Issue 10, Page 2641-2649, 15 May 2026.
What's New? Exercise releases bioactive molecules into the bloodstream that can directly slow cancer cell growth. In colon cancer, this may help limit disease progression. Here, using colon cancer cells, the authors investigated the effects of exercise‐conditioned human serum on DNA repair mechanisms. Notably, acute exercise in humans elicited systemic

Ubiquitination and deubiquitination of PCNA in response to stalling of the replication fork [PDF]

open access: yes, 2009
Following exposure of human cells to DNA damaging agents that block the progress of the replication fork, mono-ubiquitination of PCNA mediates the switch from replicative DNA polymerases to polymerases specialised for translesion synthesis. We have shown

A new map to understand deubiquitination

open access: yesBiochemical Society Transactions, 2010
Deubiquitination is a crucial mechanism in ubiquitin-mediated signalling networks. The importance of Dubs (deubiquitinating enzymes) as regulators of diverse cellular processes is becoming ever clearer as new roles are elucidated and new pathways are shown to be affected by this mechanism.

ORMDL Proteins Turnover via Proteasome and Autophagy Is Cell‐Type Dependent and Tied to Ceramide Homeostasis

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
ORMDL proteins in the endoplasmic reticulum (ER) negatively regulate serine palmitoyltransferase (SPT) activity in response to the rate of de novo sphingolipid synthesis. Disruption of ceramide homeostasis by myriocin or fumonisin B1 (FB1) appears to destabilize the ORMDL‐SPT complex, leading to ORMDL degradation as a feedback mechanism.

USP13 regulates ferroptosis in chicken follicle granulosa cells by deubiquitinating ATG7

open access: yesPoultry Science
: The development and maturation of follicles are intricately linked to egg production and reproductive performance of chickens. Granulosa cells death directly affects the development and maturation of follicles, thereby impacting the reproductive ...
