Already known for their role in RNA interference, Argonaute proteins also regulate another process that affects gene expression: alternative splicing. This is what researchers from the Laboratory “Epigenetics and Cancer” (CNRS/CEA) and the laboratory “Genetic, molecular and cellular basis of development” (Institut Pasteur/CNRS) have brought to the light. This result published in Nature Structural & Molecular Biology has been obtained in collaboration with the Center of Immunology of Marseille-Luminy (CNRS/Inserm/Université Aix-Marseille), the Institut des hautes études scientifiques and Ali Hamiche's team from the IGBMC.
