Cornelia de Lange syndrome (CdLS) is a dominantly inherited congenital malformation disorder, caused by mutations in the cohesin-loading protein NIPBL for nearly 60% of individuals with classical CdLS, and by mutations in the core cohesin components SMC1A (~5%) and SMC3 (<1%) for a smaller fraction of probands. In humans, the multisubunit complex cohesin is(More)
Centromeres are specialized chromosome domains that control chromosome segregation during mitosis, but little is known about the mechanisms underlying the maintenance of their integrity. Centromeric ultrafine anaphase bridges are physiological DNA structures thought to contain unresolved DNA catenations between the centromeres separating during anaphase.(More)
The cyclin-dependent kinase CDK11p58 is specifically expressed at G2/M phase. CDK11p58 depletion leads to different cell cycle defects such as mitotic arrest, failure in centriole duplication and centrosome maturation, and premature sister chromatid separation. We report that upon CDK11 depletion, loss of sister chromatid cohesion occurs during mitosis but(More)
We have previously found that a Tyr residue was critical for the interaction of peptides with the Kd molecule, and therefore may be acting as an anchor residue. In the present report we show that it is possible to convert a self peptide sequence into a Kd-restricted neo-antigen by a single Tyr substitution at position 2 of the peptide. This supports the(More)
Le champ de recherche « Développement, Evolution, Reproduction, Cellules Souches » est issu de la rencontre de l'embryologie classique avec la zoologie et la génétique traditionnelles et de l'apport de la biologie moléculaire, de la biologie cellulaire et, plus récemment, de la génomique. Il s'agit donc d'une recherche multidisciplinaire, transversale par(More)
