Dynamic eIF3‐S6 Phase Separation Switch Instructed by m6A Modification Drives the Molting of Locusts

open access: yesAdvanced Science, EarlyView.
This research reveals that reduced m6A modifications during insect molting trigger liquid–liquid phase separation (LLPS) of the m6A reader eIF3‐S6, which binds and stabilizes key molting mRNAs, including EcR and Cht10. Disrupting m6A or LLPS causes cuticle remodeling defects and molting failure, highlighting the synergistic control of gene expression ...

Biallelic Variants in the DARS2 Gene as a Novel Cause of Axonal Charcot–Marie–Tooth Disease

open access: yesAnnals of Neurology, EarlyView.
Objective Charcot–Marie–Tooth (CMT) disease is a heterogeneous group of genetic neuropathies, with >90 genes identified. Several aminoacyl‐tRNA synthetases have been linked to CMT. DARS2, encoding the mitochondrial aspartyl‐tRNA synthetase, has been typically associated with leukoencephalopathy with brainstem and spinal cord involvement and lactate ...

Extracellular Vesicles in Calcium Oxalate Nephrolithiasis: Emerging Biomarkers and Therapeutic Potential

open access: yesAdvanced NanoBiomed Research, EarlyView.
Kidney stones cause significant pain and healthcare costs. Current prediction, diagnosis, and treatment options are limited. Extracellular vesicles (EVs), rich in proteins, lipids, and nucleic acids, offer a promising solution. This review explores the roles of EVs in kidney stone management, highlighting their potential as biomarkers and therapeutic ...

Multiple Layers of Stress-Induced Regulation in tRNA Biology

open access: yesLife, 2016
tRNAs are the fundamental components of the translation machinery as they deliver amino acids to the ribosomes during protein synthesis. Beyond their essential function in translation, tRNAs also function in regulating gene expression, modulating ...

Selektive chemische Manipulation von Mannosyl‐ und Galaktosyl‐Queuosin in tRNAs lebender Zellen

open access: yesAngewandte Chemie, EarlyView.
Die Q‐Base in der Antikodonschleife bestimmter eukaryotischer tRNA wird weiter mannosyliert und galaktosyliert. Durch die Zufuhr chemisch manipulierter Queuinderivate zeigen wir, dass die zuckermodifizierenden Enzyme die Modifikationschemie mit hoher Regio‐ und Chemoselektivität durchführen. Zusammenfassung Queuosin ist ein hypermodifiziertes Nukleosid,

Erweiterung des Repertoires an lichtschaltbaren unnatürlichen Aminosäuren für das Enzym‐Engineering

open access: yesAngewandte Chemie, EarlyView.
Enzym‐Engineering mit lichtschaltbaren unnatürlichen Aminosäuren (lsUAs) birgt ein hohes Potenzial für Anwendungen wie die Biokatalyse. Wir erweitern hier das aktuell vorhandene Repertoire mit lsUAs, welche vielseitigere Eigenschaften aufweisen, um den Weg für eine fortschrittlichere Etablierung der Lichtkontrolle in Enzymen zu ebnen. Wir berichten die

Nuclear and mitochondrial tRNA-lookalikes in the human genome

open access: yesFrontiers in Genetics, 2014
We are interested in identifying and characterizing loci of the human genome that harbor sequences resembling known mitochondrial and nuclear tRNAs. To this end, we used the known nuclear and mitochondrial tRNA genes (the tRNA-Reference set) to search ...

Selective Chemical Manipulation of Mannosyl‐ and Galactosyl‐Queuosine in tRNAs of Living Cells

open access: yesAngewandte Chemie International Edition, EarlyView.
The Q‐base in the anticodon loop of certain eukaryotic tRNA is further mannosylated and galactosylated. Using feeding of chemically manipulated queuine derivatives, we show that the sugar‐modifying enzymes perform the modification chemistry with high regio‐ and chemoselectivity.
