L’ubiquitylation consiste en l’attachement covalent de l’ubiquitine sur d’autres protéines. Ce processus fait intervenir successivement trois familles d'enzymes : d’activation (E1s), de conjugaison (E2s) et de ligation (E3s) de l’ubiquitine. Lors de ma thèse, je m’intéresse au réseau d’enzymes d’ubiquitylation qui régule Cse4, l’histone variant localisée spécifiquement au centromère. Cse4 est une protéine essentielle qui permet une ségrégation correcte des chromosomes. Lorsqu’elle est trop exprimée, Cse4 peut se localiser sur la chromatine noncentromérique ce qui entraîne une instabilité génétique observée dans de nombreux cancers. Chez la levure, l’ubiquitylation empêche cette mauvaise localisation en menant à la dégradation de Cse4, mais ...
