Protein domains required for nuclear and sub-nuclear targeting of subunits of splicing factor SF3a

Protein domains required for nuclear and sub-nuclear targeting of subunits of splicing factor SF3a

Abstract

Le but de ma thèse a été d'identifier les signaux responsables de l'adressage du complexe de splicing SF3a vers le noyau et d'étudier les domaines de ses sous-unités qui sont importants pour une localisation correcte du complexe. J'ai démontré que l'import de SF3a120 dans le noyau est indépendant de ses interactions avec les plus petites sous-unités et j'ai identifié une séquence de localisation nucléaire. J'ai démontré l'implication d'une région de 84 acides aminés, contenant le domaine SAP, dans l'adressage de SF3a60 vers les corps de Cajal (CBs). Cette même région est également suffisante pour envoyer deux protéines reporteurs vers les CBs, ce qui prouve que la région est nécessaire et suffisante pour l'adressage du complexe SF3a entier aux CBs. D'autre part, la partie amino-terminale de la coilin montre des similitudes de séquence avec le domaine SAP, ce qui indique une fonction similaire pour les séquences communes entre SF3a60 et la coilin.
