Investigating the intra-molecular and inter-molecular effects of post-translational modifications on intrinsically disordered protein regions and structured protein regions
Post-translational modifications (PTMs) play a pivotal role in regulating protein structure, interaction, and function. Aberrant PTM patterns are associated with diseases. Moreover, individual PTMs have a complex interaction with each other, known as PTM c ...
EPFL2024Epigenetic plasticity as a signature for memory allocation
Long-lasting memories are stored in a small set of neurons scattered throughout the brain, so-called engram cells. To define a stable engram each region of the brain involved in memory storage recruits between 5 and 20 percent of excitatory neurons. In par ...
EPFL2022Epigenetic memory aids: Synaptic and molecular effects of HDAC inhibition that support memory formation
Learning and memory rely on synaptic communication in which intracellular signals are transported to the nucleus to stimulate transcriptional activation. Memory induced transcriptional increases are accompanied by alterations to the epigenetic landscape an ...
EPFL2022Epigenetic remodelling of enhancers in response to estrogen deprivation and re-stimulation
Estrogen hormones are implicated in a majority of breast cancers and estrogen receptor alpha (ER), the main nuclear factor mediating estrogen signaling, orchestrates a complex molecular circuitry that is not yet fully elucidated. Here, we investigated geno ...
OXFORD UNIV PRESS2021NCoR1 Protects Mice From Dextran Sodium Sulfate Induced Colitis by Guarding Colonic Crypt Cells From Luminal Insult
BACKGROUND & AIMS: Colonic stem cells are essential for producing the mucosal lining, which in turn protects stem cells from insult by luminal factors. Discovery of genetic and biochemical events that control stem cell proliferation and differentiation can ...
2020AMBER and CHARMM Force Fields Inconsistently Portray the Microscopic Details of Phosphorylation
Phosphorylation of serine, threonine, and tyrosine is one of the most frequently occurring and crucial post-translational modifications of proteins often associated with important structural and functional changes. We investigated the direct effect of phos ...
AMER CHEMICAL SOC2019Protein Semisynthesis Provides Access to Tau Disease-Associated Post-translational Modifications (PTMs) and Paves the Way to Deciphering the Tau PTM Code in Health and Diseased States
Hilal Lashuel, Mahmood Haj Yahya
The microtubule-associated protein Tau plays a central role in neurodegeneration and is a leading therapeutic target for the treatment of Alzheimer’s disease (AD). Several lines of evidence suggest that post-translational modifications (PTMs) regulate the ...
2018Mutant Exon1 Huntingtin Aggregation is Regulated by T3 Phosphorylation-Induced Structural Changes and Crosstalk between T3 Phosphorylation and Acetylation at K6
Giovanni Dietler, Hilal Lashuel, Francesco Simone Ruggeri, Anass Chiki, Sean Michael Deguire, Urszula Beata Cendrowska, Annalisa Ansaloni, Ritwik Burai, Sophie Vieweg
Herein, we used protein semisynthesis to investigate, for the first time, the effect of lysine acetylation and phosphorylation, as well as the crosstalk between these modifications on the structure and aggregation of mutant huntingtin exon1 (Httex1). Our r ...
Wiley-Blackwell2017Heterochromatin protein 1 recruitment and chromatin conformational dynamics at the single-molecule level
Chromatin is the template on which DNA-associated transactions take place in eukaryotic organisms. Nucleosomes consisting of the four histones H2A, H2B, H3 and H4 each organize ~150bp of DNA and constitute a first layer of chromatin. The three-dimensional ...
