Neddylation Targets and Stabilizes NLRP3 to Augment Inflammasome‐Mediated Colitis and Mood Disorder

open access: yesAdvanced Science, Volume 13, Issue 16, 18 March 2026.
NLRP3 inflammasome contributes to colitis and mood disorder. This study demonstrates that neddylation targets NLRP3 at K287, which hinders its interaction with K48‐linked ubiquitination E3 Trim31 and thereby stabilizes it. Neddylation blockade in myeloid cells and microglia mitigates DSS‐induced colitis and psychological stress‐induced anxiety‐like ...

UCHL3 Regulates Topoisomerase-Induced Chromosomal Break Repair by Controlling TDP1 Proteostasis

open access: yesCell Reports, 2018
Summary: Genomic damage can feature DNA-protein crosslinks whereby their acute accumulation is utilized to treat cancer and progressive accumulation causes neurodegeneration.

TBK1 Induces the Formation of Optineurin Filaments That Condensate with Polyubiquitin and LC3 for Cargo Sequestration

open access: yesAdvanced Science, Volume 13, Issue 16, 18 March 2026.
Phosphorylation of Optineurin by TBK1 induces the formation of filaments that condensate upon binding to linear polyubiquitin. Membrane‐anchored LC3 partitions into these condensates, suggesting that phase separation of filamentous Optineurin with ubiquitylated cargo promotes the sequestration of cargo and its subsequent alignment with LC3‐positive ...

Drosophila IAP1-mediated ubiquitylation controls activation of the initiator caspase DRONC independent of protein degradation.

open access: yesPLoS Genetics, 2011
Ubiquitylation targets proteins for proteasome-mediated degradation and plays important roles in many biological processes including apoptosis. However, non-proteolytic functions of ubiquitylation are also known. In Drosophila, the inhibitor of apoptosis

American College of Rheumatology Guidance Statement for Diagnosis and Management of VEXAS Developed by the International VEXAS Working Group Expert Panel

open access: yesArthritis &Rheumatology, Volume 78, Issue 3, Page 509-522, March 2026.
Objective Vacuoles E1 enzyme X‐linked autoinflammatory somatic syndrome (VEXAS) is a recently identified rare genetic disorder associated with somatic mutations in the UBA1 gene. VEXAS presents with a combination of inflammatory and hematologic manifestations, leading to increased morbidity and mortality.

Synthesis of Isomeric Phosphoubiquitin Chains Reveals that Phosphorylation Controls Deubiquitinase Activity and Specificity

open access: yesCell Reports, 2016
Ubiquitin is post-translationally modified by phosphorylation at several sites, but the consequences of these modifications are largely unknown. Here, we synthesize multi-milligram quantities of ubiquitin phosphorylated at serine 20, serine 57, and ...

CMA‐mediated USP9X degradation promotes SHH medulloblastoma progression by facilitating SUFU ubiquitination

open access: yesClinical and Translational Medicine, Volume 16, Issue 3, March 2026.
Deubiquitinase USP9X suppresses SHH Medulloblastoma progression by facilitating SUFU ubiquitination. SHH promotes USP9X degradation through the CMA pathway. Combined inhibition of CMA and SHH pathway had a synergically therapeutic effect on SHH Medulloblastoma.

Determination of Cellular Phosphatidylinositol-3-phosphate (PI3P) Levels Using a Fluorescently Labelled Selective PI3P Binding Domain (PX)

open access: yesBio-Protocol, 2016
The lipid Phosphatidylinositol-3-phosphate [PtdIns3P or PI(3)P] plays many membrane trafficking roles and is primarily produced by the Class III PI3K, VPS34. Determining the level of cellular PI(3)P however can be complex.

The Role of One‐Carbon Metabolism in Cancer and Its Therapeutic Significance

open access: yesMedComm – Oncology, Volume 5, Issue 1, March 2026.
One‐Carbon metabolism in T‐cell activation and tumor competition. T‐cell activation shifts metabolic pathways, promoting anabolic metabolism and bioenergetic capacity. One‐carbon metabolism plays a crucial role in histone and DNA methylation in activated T cells.

Functional Divergence of the Arg/N‐Degron Pathway Between the Crop Brassica rapa and the Model Plant Arabidopsis thaliana

open access: yesPlant Direct, Volume 10, Issue 3, March 2026.
ABSTRACT The ubiquitin‐dependent Arg/N‐degron pathway relates the stability of a substrate protein to the nature of its N‐terminal amino acid residue or its biochemical modifications, with some N‐terminal residues being recognized by specific E3 ubiquitin ligases, resulting in the ubiquitylation and degradation of the substrate protein.
