CMG helicase disassembly is essential and driven by two pathways in budding yeast
The EMBO JournalThe CMG helicase is the stable core of the eukaryotic replisome and is ubiquitylated and disassembled during DNA replication termination. Fungi and animals use different enzymes to ubiquitylate the Mcm7 subunit of CMG, suggesting that CMG ubiquitylation ...

Localization-Dependent and -Independent Roles of SLX4 in Regulating Telomeres
Cell Reports, 2013 SLX4, a scaffold for structure-specific DNA repair nucleases, is important for several types of DNA repair. Many repair proteins bind to sites of DNA damage, resulting in subnuclear “foci,” but SLX4 forms foci in human cells even without DNA damage ...

Insights Into the Role of Lysine Acetylation of Non‐Histone Proteins in Plant Immunity
Plant, Cell &Environment, EarlyView.ABSTRACT Plant immunity is regulated by numerous transcriptional and posttranslational mechanisms. Among these, lysine acetylation, which is controlled by lysine acetyltransferases (KATs) and lysine deacetylases (KDACs), has been extensively studied, particularly in the context of epigenetic regulation through histone acetylation.

Targeted dephosphorylation of SMAD3 as an approach to impede TGF-β signaling
iScienceSummary: TGF-β (transforming growth factor-β) signaling is involved in a myriad of cellular processes and its dysregulation has been implicated in many human diseases, including fibrosis and cancer.

The Journal of Physiology, EarlyView.Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

PINK1 regulated mitophagy is evident in skeletal muscles
Autophagy ReportsPINK1, mutated in familial forms of Parkinson’s disease, initiates mitophagy following mitochondrial depolarization. However, it is difficult to monitor this pathway physiologically in mice as loss of PINK1 does not alter basal mitophagy levels in most ...

F1000Research, 2020 Protein ubiquitylation is essential for the maintenance of cellular homeostasis. E3 ubiquitin ligases are key components of the enzymatic machinery catalyzing the attachment of ubiquitin to substrate proteins. Consequently, enzymatic dysfunction has been

Molecular Oncology, Volume 20, Issue 3, Page 637-667, March 2026.HDAC4 is degraded by the E3 ligase FBXW7. In colorectal cancer, FBXW7 mutations prevent HDAC4 degradation, leading to oxaliplatin resistance. Forced degradation of HDAC4 using a PROTAC compound restores drug sensitivity by resetting the super‐enhancer landscape, reprogramming the epigenetic state of FBXW7‐mutated cells to resemble oxaliplatin ...

UbiProt: a database of ubiquitylated proteins
BMC Bioinformatics, 2007 Background Post-translational protein modification with ubiquitin, or ubiquitylation, is one of the hottest topics in a modern biology due to a dramatic impact on diverse metabolic pathways and involvement in pathogenesis of severe human diseases.
