3′UTR variants of ALS‐linked RNAs modify subcellular and cellular phenotypes
Our study demonstrates that alternative 3′UTR variants of ALS‐linked transcripts modulate subcellular RNA localization and cytoskeletal architecture. NEFH 3′UTR‐Long promotes nuclear RNA clustering, while SOD1 3′UTR‐Long reduces filopodia formation. These results suggest that 3′UTRs, independent of coding sequences, can influence neuronal phenotypes ...

FPR2 activation mediates NOX‐dependent LAT1 expression and, in turn, promotes mTORC1 signaling. Upon stimulation with WKYMVm, the FPR2‐NOX2‐ROS axis upregulates LAT1 via increased c‐Myc phosphorylation and decreased miR‐126. Additionally, it promotes CD98 translocation to the plasma membrane.

Selective targeting of cortactin tandem repeat acetylation by human lysine deacetylases
Cortactin function is regulated by acetylation at several lysine residues within its tandem repeat region. Using genetic code expansion to generate cortactin variants containing precisely defined acetylation marks, we show that HDAC6 is the primary enzyme removing these modifications, with SIRT1 and SIRT2 also acting at selected sites but with lower ...

Harnessing S. cerevisiae to advance the engineering of pentatricopeptide repeat proteins
Heterologous expression systems have been instrumental in furthering our understanding of plant RNA editing proteins. In this commentary, we discuss how the establishment of yeast as a model for studying plant RNA editing by Ramanathan et al. could advance the engineering of pentatricopeptide repeat proteins, and how in return pentatricopeptide repeat ...

Proteostasis of organelles in aging and disease
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

Genetic encoding of noncanonical amino acids (ncAA) enables their site‐specific installation in proteins. This work compares the nuclear magnetic resonance (NMR) performance of different ncAAs in a large protein−DNA complex (~ 100 kDa) without isotope labelling. The ncAAs deliver readily detectable NMR signals in the complex between E.

GCN2 in proteostasis: structural logic, signalling networks and disease
Threats to protein synthesis activate the kinase GCN2, initiating the integrated stress response (ISR). GCN2 is triggered by stalled ribosomes and uncharged tRNAs, which accumulate when amino acids are scarce. The ISR adjusts cellular physiology by promoting redox balance, protein quality control, and mitochondrial optimisation.
