Proteostasis of organelles in aging and disease

open access: yesThe 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 ...

Uncovering a previously unknown function of polyphosphate in polyadenylated RNA‐induced amyloidogenesis of Hfq

open access: yesThe 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

open access: yesThe 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.

Functional characterization of 42 CK2α de novo variants associated with Okur‐Chung neurodevelopmental syndrome

open access: yesThe FEBS Journal, EarlyView.
Okur‐Chung neurodevelopmental syndrome (OCNDS) is a neurodevelopmental disorder associated with mutations in the gene coding for Protein kinase CK2α. In this work, 42 variants of CK2α associated with OCNDS were characterized in vitro. This included determination of catalytic activity and CK2α/CK2β‐interaction as well as an assessment of evolutionary ...

Water, water, every where—the advent of hydrated pili structure

open access: yesThe FEBS Journal, EarlyView.
Protein structure is defined by its surrounding water. Naturally, this is also true for the gigantic protein filaments that pathogenic bacteria use to attach to and colonize their host cells. Structures of these filaments for which water can be identified with high confidence have stayed elusive for the longest time.
