Les protéines EPAC sont des facteurs d'échange de nucléotides guanine (GEFs), directement activées par le second messager AMP cyclique (AMPc), qui activent les petites GTPases Rap à la périphérie des membranes cellulaires.La protéine EPAC1, principalement exprimée dans le cœur, joue un rôle important dans la physiologie et la physiopathologie cardio-vasculaire, et constitue ainsi une cible thérapeutique attractive. L'activation d'EPAC1 par l'AMPc se traduit par un changement de conformation de grande amplitude. Des travaux récents de l'équipe ont permis de découvrir qu'EPAC1 est aussi régulée par les membranes biologiques. Plus qu'un simple lieu de « rendez-vous » entre la GEF et sa GTPase, les membranes jouent donc un rôle essentiel dans l...
