Pintard Lab – Microtubule-binding domains in Katanin p80 subunit are essential for severing activity in C. elegans

Home publis, News13 February 2024
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…

Courtier Lab – Higher evolutionary dynamics of gene copy number for Drosophila glue genes located near short repeat sequences

Home publis, News13 February 2024
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…

Wassmann Lab – Qualitative rather than quantitative phosphoregulation shapes the end of meiosis I in budding yeast

Home publis, News13 February 2024
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…
