Ladoux/Mege Lab – A multicellular star-shaped actin network underpins epithelial organization and connectivity

The Ladoux/Mege Lab contributed to the publication of a new article in Nature Communications: A multicellular star-shaped actin network underpins epithelial organization and connectivity Abstract: Epithelial tissues withstand external stresses while maintaining structural stability. Bicellular junctions and the actomyosin network support epithelial integrity, packing and remodelling. While their role in development and disease are well studied, their…

ProtéoSeine – Structural and functional characterization of CREB-binding protein (CREBBP) as a histone propionyltransferase

The ProteoSeine platform contributed to the publication of a new article in Journal of biological chemistry: Structural and functional characterization of CREB-binding protein (CREBBP) as a histone propionyltransferase Abstract: In addition to histone acetylation, histone lysine propionylation (such as the H3K18Pr mark) has recently attracted significant attention as a common and abundant modification linking the cellular metabolic…

Palancade Lab & ProtéoSeine – Cellular imbalance of specific RNA binding proteins associates with harmful R-loops

The Palancade Lab and the ProteoSeine platform contributed to the publication of a new article in PLOS genetics: Cellular imbalance of specific RNA binding proteins associates with harmful R-loops Abstract: Understanding how the assembly of nascent mRNA into a ribonucleoprotein (mRNP) influences R-loop homeostasis is crucial for gaining insight into the cellular mechanisms that prevent genome instability.…

Courtier Lab – Evolution of a novel left-right asymmetry in organ size by co-option of a tissue rotation process

The Courtier Lab published a new article in Development: Evolution of a novel left-right asymmetry in organ size by co-option of a tissue rotation process Abstract: Left-right asymmetries have repeatedly evolved in diverse animals and affect the position, shape or size of specific organs. How novel left-right asymmetries arise remains unknown. Here, we examined Drosophila pachea, where males…

Raote Lab – TUG protein acts through a disordered region to organize the early secretory pathway

The Raote Lab contributes to the publication of a new article in Nature communications: TUG protein acts through a disordered region to organize the early secretory pathway Abstract: The Endoplasmic Reticulum (ER)-Golgi Intermediate Compartment (ERGIC) is a network of tubules and vesicles known for producing COPI vesicles and receiving COPII vesicles from the ER. Much about its…

Guichet Lab – Sheltered load in fungal mating-type chromosomes revealed by fitness experiments

The Guichet Lab contributed to a new article published in Journal of Evolutionary Biology: Sheltered load in fungal mating-type chromosomes revealed by fitness experiments Abstract: Sex chromosomes and mating-type chromosomes can carry large regions with suppressed recombination. As a result of a lower efficacy of selection, recessive deleterious mutations are expected to accumulate in these non-recombining regions.…

Greenberg Lab – PIK3R1 and G0S2 are human placenta-specific imprinted genes associated with germline-inherited maternal DNA methylation

The Greenberg lab contributed to a new publication in Epigenetics: PIK3R1 and G0S2 are human placenta-specific imprinted genes associated with germline-inherited maternal DNA methylation   Abstract: Genomic imprinting is the parent-of-origin specific monoallelic expression of genes that result from complex epigenetic interactions. It is often achieved by monoallelic 5-methylcytosine, resulting in the formation of differentially methylated regions (DMRs). These show a…

Romet-Lemonne/Jégou Lab – Continuous self-repair protects vimentin intermediate filaments from fragmentation

The Romet-Lemonne/Jégou Lab published a new publication in PNAS: Continuous self-repair protects vimentin intermediate filaments from fragmentation Abstract: Intermediate filaments are key regulators of cell mechanics. Vimentin, a type of intermediate filament expressed in mesenchymal cells and involved in migration, forms a dense network in the cytoplasm that is constantly remodeling through filament transport, elongation/shortening, and subunit…
