The ubiquitin ligase RNF115 is required for the clearance of damaged lysosomes

FEBS Letters, EarlyView.
Upon lysosomal rupture, an E3 ubiquitin ligase RNF115 translocates from the cytosol to the damaged lysosomal membrane. Moreover, RNF115 depletion impairs the clearance of damaged lysosomes, identifying it as a key regulator of lysosomal quality control.

Loss-of-function cancer-linked mutations in the EIF4G2 non-canonical translation initiation factor

Life Science Alliance
This work identifies missense mutations in the translation initiation factor EIF4G2 gene in cancer, showing loss-of-function effects on binding to interacting proteins and translational activity.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Cap-dependent translation initiation monitored in living cells

Nature Communications, 2022
mRNA translation is tightly regulated to preserve cellular homeostasis. Here live-cell spectroscopy and single-particle tracking are combined to interrogate the binding dynamics of endogenous initiation factors to mRNAs 5’cap, revealing the sequence of ...

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

The Plasmodium eukaryotic initiation factor-2α kinase IK2 controls the latency of sporozoites in the mosquito salivary glands [PDF]

, 2010
Sporozoites, the invasive form of malaria parasites transmitted by mosquitoes, are quiescent while in the insect salivary glands. Sporozoites only differentiate inside of the hepatocytes of the mammalian host. We show that sporozoite latency is an active

Translation initiation or elongation inhibition triggers contrasting effects on Caenorhabditis elegans survival during pathogen infection

mBio
Diverse microbial pathogens are known to attenuate host protein synthesis. Consequently, the host mounts a defense response against protein translation inhibition, leading to increased transcript levels of immune genes.

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Universal scanning-free initiation of eukaryote protein translation–a new normal

Biomolecular Concepts, 2021
A unique feature of eukaryote initiation of protein translation is a so-called scanning of 5′-untranslated region (5′-UTR) by a ribosome initiation complex to enable bound Met-tRNAi access to the initiation codon located further downstream.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...
