The FEBS Journal, EarlyView.Proteostasis ensures proper protein folding, modification, and degradation, while its impairment triggers ER stress. Chronic ER stress and maladaptive UPR via the CHOP–ERO1 axis remodel ERMCs, altering calcium signaling and mitochondrial metabolism.

Proteostasis of organelles in aging and disease
The FEBS Journal, EarlyView.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 ...

The FEBS Journal, EarlyView.Alpha‐crystallin B chain (CRYAB) has been reported to stabilize mothers against decapentaplegic homolog 4 (SMAD4) in transforming growth factor‐β (TGF‐β) signaling, enabling target gene transcription. We show nuclear CRYAB–SMAD4 interaction for the first time in human skeletal muscle fibers and its regulation by exercise.

The FEBS Journal, EarlyView.In this issue, Elmaleh et al. demonstrate that the E425K mutation in DNAJC7, associated with amyotrophic lateral sclerosis, selectively abolishes one of a co‐chaperone's dual functions. High‐resolution NMR confirmed that the mutation leaves the protein's structure intact while paralyzing its communication with the Hsp70 machinery.

GCN2 in proteostasis: structural logic, signalling networks and disease
The FEBS Journal, EarlyView.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.

The FEBS Journal, EarlyView.Exercise‐related microRNAs cel‐miR‐249‐3p and cel‐miR‐77‐5p in C. elegans regulate lifespan, fitness, mitochondrial morphology and membrane potential. Although lacking direct mammalian orthologs, H2O2‐induced microRNAs mmu‐miR‐181a‐5p and mmu‐miR‐378a‐3p regulate myogenesis, autophagy, mitochondrial content and respiration in murine myoblasts ...

The FEBS Journal, EarlyView.The eukaryote‐specific N‐terminal domain (NTD) of eS31 uses two distinct strategies to maintain translation fidelity. During elongation, a positively charged “hotspot” fine‐tunes the selection of incoming aa‐tRNA. During termination, the entire NTD acts as a structural scaffold to ensure the correct positioning of the release factor eRF1.

The FEBS Journal, EarlyView.Divalent metal transporter 1 (Dmt1) maintains iron homeostasis and lysosomal proteostasis required for physiological Notch receptor–ligand signaling. Dmt1 loss lowers iron storage capacity (ferritin), increasing intracellular Fe2+, driving ROS and lipid peroxidation, and leading to lysosomal/mitochondrial dysfunction.
