The FEBS Journal, EarlyView.Polyphosphate interaction with Hfq and RNA drives phase separation and amyloid self‐assembly, uncovering a previously unrecognized role for polyP in bacterial stress responses. Our findings reveal new insights into the molecular mechanisms of RNA‐mediated phase separation, highlighting the role of polyP as a key modulator of this process. Polyphosphate

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.

Degradomics for large‐scale mechanistic insights on proteases and proteolysis in human health
The FEBS Journal, EarlyView.Proteolysis has an important role in human disease but remains relatively unexplored. Degradomics, the uncovering of proteolysis in tissues, cells, and proteins, uses mass spectrometry‐based terminomics to identify protein termini occurring therein (forward degradomics) and to define the actions of proteases (reverse degradomics).

Post‐transcriptional regulatory networks: The dynamic interplay of RNA‐binding proteins
The FEBS Journal, EarlyView.Post‐transcriptional gene expression regulation is controlled by RNA‐binding proteins (RBPs), which influence many processes including splicing, localization, translation, and decay. Rather than acting alone, RBPs bind RNAs combinatorially, forming complex, context‐dependent regulatory networks.

Spatially resolved mapping of histones reveals selective neuronal response in Rett syndrome
The FEBS Journal, EarlyView.Loss of Mecp2 function is associated with Rett syndrome (RTT). MeCP2 regulates chromatin, yet its influence on histone composition and dynamics is unclear. Combining MALDI‐MSI with LCM–LC–MS/MS, we mapped histone proteoforms across the dentate gyrus, cornu ammonis, and cerebellum in two mouse models of RTT.

Biogenesis of TNF‐α‐insights into proteostasis and inflammation
The FEBS Journal, EarlyView.TNF‐α biogenesis, trafficking, and signalling are tightly and reciprocally coupled to cellular proteostasis systems, including ER chaperones and endoplasmic reticulum‐associated degradation. This bidirectional crosstalk determines whether TNF‐α responses are adaptive or proteotoxic.

The FEBS Journal, EarlyView.Fragile X messenger ribonucleoprotein 1 (FMRP) is a multidomain RNA‐binding protein associated with Fragile X Syndrome (FXS). We found that its N‐terminal structured region has an intrinsic propensity to undergo liquid–liquid phase separation and fibril formation. FXS‐associated mutations perturb protein stability and aggregation propensity, suggesting
