The Pintard lab recently published a new article in Journal of Cell Biology: Microtubule-binding domains in Katanin p80 subunit are essential for severing activity in C. elegans   Abstract: Microtubule-severing enzymes (MSEs), such as Katanin, Spastin, and Fidgetin play essential roles in cell division and neurogenesis. They damage the microtubule (MT) lattice, which can either destroy or amplify the…

The Courtier lab recently published a new article in BMC Ecology and Evolution: Higher evolutionary dynamics of gene copy number for Drosophila glue genes located near short repeat sequences Abstract: Background During evolution, genes can experience duplications, losses, inversions and gene conversions. Why certain genes are more dynamic than others is poorly understood. Here we examine…

The Wassmann lab published a new article in EMBO: Qualitative rather than quantitative phosphoregulation shapes the end of meiosis I in budding yeast   Abstract: Exit from mitosis is brought about by dramatic changes in the phosphoproteome landscape. A drop in Cyclin-dependent kinase (Cdk) activity, the master regulatory kinase, and activation of counteracting phosphatases such as Cdc14 in budding…

The Romet-Lemonne/Jégou Lab contributed to the publication of a new article in Nature structural & molecular biology: Cortactin stabilizes actin branches by bridging activated Arp2/3 to its nucleated actin filament   Résumé: Regulation of the assembly and turnover of branched actin filament networks nucleated by the Arp2/3 complex is essential during many cellular processes, including cell migration and…

The Guichet Lab published a new article in Cells: The Importance of the Position of the Nucleus in Drosophila  Oocyte Development Abstract: Oogenesis is a developmental process leading to the formation of an oocyte, a haploid gamete, which upon fertilisation and sperm entry allows the male and the female pronuclei to fuse and give rise to a zygote.…

The Romet-Lemonne/Jégou Lab published a new article in Science Advances: Regeneration of actin filament branches from the same Arp2/3 complex Abstract: Branched actin filaments are found in many key cellular structures. Branches are nucleated by the Arp2/3 complex activated by nucleation-promoting factor (NPF) proteins and bound to the side of preexisting “mother” filaments. Over time, branches dissociate…

The Palancade Lab recently published a new review in Current Opinion in Genetics & Development: On the edge: how nuclear pore complexes rule genome stability   Abstract: Nuclear organization has emerged as a critical layer in the coordination of DNA repair activities. Distinct types of DNA lesions have notably been shown to relocate at the vicinity of nuclear…

The Greenberg contributed to the publication of a new article in Nature Structural & Molecular biology: DNA methylation restricts coordinated germline and neural fates in embryonic stem cell differentiation   Abstract: As embryonic stem cells (ESCs) transition from naive to primed pluripotency during early mammalian development, they acquire high DNA methylation levels. During this transition, the germline is…

The Camadro lab and the ProtéoSeine platform contirbuted to the publication of a new article in eBioMedicine: Multiomic analysis in fibroblasts of patients with inborn errors of cobalamin metabolism reveals concordance with clinical and metabolic variability   Abstract: Background The high variability in clinical and metabolic presentations of inborn errors of cobalamin (cbl) metabolism (IECM), such as the cblC/epicblC types with…

The Raote lab contributed to the publicaiton of a new article in PNAS : A model for collagen secretion by intercompartmental continuities   Abstract: Newly synthesized secretory proteins are exported from the endoplasmic reticulum (ER) at specialized subcompartments called exit sites (ERES). Cargoes like procollagen are too large for export by the standard COPII-coated vesicle of 60…
