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.

Noroviruses Co-opt the Function of Host Proteins VAPA and VAPB for Replication via a Phenylalanine–Phenylalanine-Acidic-Tract-Motif Mimic in Nonstructural Viral Protein NS1/2

mBio, 2017
The Norovirus genus contains important human pathogens, but the role of host pathways in norovirus replication is largely unknown. Murine noroviruses provide the opportunity to study norovirus replication in cell culture and in small animals.

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.

Nucleocapsid protein captures DDX5 and RNMT facilitating viral RNA synthesis and viral protein translation for coronavirus replication

mBio
Coronaviruses (CoVs) hijack host RNA-binding proteins (RBPs) to facilitate their replication, but the viral proteins and host RBDs that participate in the synthesis of viral RNA and protein are unclear.

Detection of Posttranslational Modifications of Replication Protein A [PDF]

, 2012
Replication Protein A (RPA) is a single-strand DNA-binding protein that is found in all eukaryotes. RPA is subjected to multiple posttranslational modifications including serine- and threonine-phosphorylation, poly-ADP ribosylation, and SUMOylation. These modifications are believed to regulate RPA activity through modulating interactions with DNA and ...

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Heat shock protein A1L restricts influenza A virus by ubiquitination of NA

Journal of Virology
Neuraminidase (NA) protein of influenza A virus (IAV), a tetrameric envelope glycoprotein critical for viral release and spread, has well-characterized enzymatic functions but poorly resolved host-pathogen interactions.

DNA Copy-Number Control through Inhibition of Replication Fork Progression

Cell Reports, 2014
Proper control of DNA replication is essential to ensure faithful transmission of genetic material and prevent chromosomal aberrations that can drive cancer progression and developmental disorders.

Replication Enhancer Requirement for Recognition of Heterologous Replication Origin by an Initiator Protein

Plasmid, 1995
In the pT181 plasmid family, the replication initiation protein (Rep) encoded by each plasmid recognizes only its cognate origin, unless the Rep protein is expressed at abnormally high levels. Heterologous recognition of the origin of the pC221 plasmid by the RepC protein of the pT181 plasmid requires that cmp, the pT181 replication enhancer, be ...

Transcriptional network analysis of PTEN‐protein‐deficient prostate tumors reveals robust stromal reprogramming and signs of senescent paracrine communication

Molecular Oncology, EarlyView.
Combining PTEN protein assessment and transcriptomic profiling of prostate tumors, we uncovered a network enriched in senescence and extracellular matrix (ECM) programs associated with PTEN loss and conserved in a mouse model. We show that PTEN‐deficient cells trigger paracrine remodeling of the surrounding stroma and this information could help ...
