RNF138‐Mediated Ubiquitination and Degradation of NS5 Restricts Tick‐Borne Encephalitis Virus Infection

Advanced Science, EarlyView.
Host‐specific compatibility between RNF138‐like proteins and flavivirus NS5 determines NS5 stability. Mammalian RNF138 but not arthropod homologs recognizes and induces conserved NS5/RdRp K48‐linked ubiquitination and proteasomal degradation, thereby restricting viral replication. Ectopic RNF138 in mice attenuates TBEV‐induced pathogenesis. (Created in

Ubiquitin-activating enzyme UBA1 is required for cellular response to DNA damage [PDF]

Cell Cycle, 2012
The cellular DNA damage response (DDR) machinery that maintains genomic integrity and prevents severe pathologies, including cancer, is orchestrated by signaling through protein modifications. Protein ubiquitylation regulates repair of DNA double-strand breaks (DSBs), toxic lesions caused by various metabolic as well as environmental insults such as ...

Uba1: A Potential Ubiquitin-like Activator Protein of Urm1 in Toxoplasma gondii

International Journal of Molecular Sciences, 2022
We had shown in our previous study that TgUrm1 (ubiquitin-related Modifier 1) was involved in the regulation of anti-oxidant stress in Toxoplasma gondii by conjugating with TgAhp1. It is generally believed that Urm1 binds to target proteins through a mechanism involving Uba (ubiquitin-like activator protein).

Therapeutic Outcomes in VEXAS Syndrome: A Multicenter Comparative Cohort of Allogeneic Hematopoietic Stem Cell Transplantation and Hypomethylating Agents

American Journal of Hematology, EarlyView.
ABSTRACT Hypomethylating agents (HMA) and allogeneic hematopoietic stem cell transplantation (alloHSCT) have both demonstrated remissions in VEXAS; however, comparative data is lacking. We conducted a multicenter, retrospective analysis of 66 patients diagnosed with VEXAS syndrome treated with HMA (n = 35) or alloHSCT (n = 31). Baseline characteristics

Ubiquitin-Like Modifier Activating Enzyme 1 as a Novel Diagnostic and Prognostic Indicator That Correlates With Ferroptosis and the Malignant Phenotypes of Liver Cancer Cells

Frontiers in Oncology, 2020
PurposeFerroptosis is a type of cell death that is iron dependent, a characteristic that distinguishes it from necrosis, apoptosis, and autophagy. However, the ferroptotic mechanisms for hepatitis B virus-associated hepatocellular carcinoma (HCC) remain ...

Synthetic Strategies for Activity‐Based Probes to Decode Ubiquitin‐Like Modifiers

Chemistry – A European Journal, EarlyView.
ABSTRACT Ubiquitin‐like proteins (Ubls) such as SUMO, NEDD8, ISG15, URM1, UFM1, FAT10, ATG8/ATG12, and FUBI are essential regulators of cellular homeostasis, controlling processes from protein stability and trafficking to immune signaling and autophagy.

SPROUTS_DB: An Implemented Database of Contaminants for Extracellular Vesicle Proteomics Studies

PROTEOMICS, EarlyView.
ABSTRACT Current proteomics techniques allow rapid identification and quantification of proteins within any given biological source. However, LC–MS/MS proteomics is vulnerable to laboratory and sample‐associated contaminants. Therefore, accurate identification and annotation of such contaminants is crucial for development of reliable databases ...

UBA1 Mutations Identify a Rare but Distinct Subtype of Myelodysplastic Syndromes

Blood, 2023
Background Mutations in UBA1 are associated with VEXAS (Vacuoles, E1 enzyme, X-linked, Autoinflammatory, Somatic) syndrome, an adult-onset inflammatory disorder (Beck DB et al. NEJM 2020). Approximately 40% of VEXAS patients are also diagnosed with myelodysplastic syndromes (MDS).
