Actin dynamics is a tightly regulated process involved in various cellular events including biogenesis of clathrin-coated, AP-1 (adaptor protein 1)-coated transport carriers connecting the trans-Golgi network (TGN) and the endocytic pathway. However, the mechanisms coordinating coat assembly, membrane and actin remodelling during post-TGN transport remain(More)
The exchange of proteins and lipids between the trans-Golgi network (TGN) and the endosomal system requires multiple cellular machines, whose activities are coordinated in space and time to generate pleomorphic, tubulo-vesicular carriers that deliver their content to their target compartments. These machines and their associated protein networks are(More)
Septins (SEPTs) form a family of GTP-binding proteins implicated in cytoskeleton and membrane organization, cell division and host/pathogen interactions. The precise function of many family members remains elusive. We show that SEPT6 and SEPT7 complexes bound to F-actin regulate protein sorting during multivesicular body (MVB) biogenesis. These complexes(More)

(in English) 33(1):1-18.Viruses that infect plants are generally single-stranded (ss) positive-sense RNA viruses. The accumulation of the virus progeny inside the plant cells involves translation, replication, cell–to-cell and long-distance movement of viral sequences.(More)
Transport carriers regulate the bidirectional flow of membrane between the compartments of the secretory and endocytic pathways. Their biogenesis relies on the recruitment of a number of cytosolic proteins and protein complexes on specific membrane microdomains with defined protein and lipid compositions. The timely assembly of these cellular machines onto(More)
Clathrin/adaptor protein-1-coated carriers connect the secretory and the endocytic pathways. Carrier biogenesis relies on distinct protein networks changing membrane shape at the trans-Golgi network, each regulating coat assembly, F-actin-based mechanical forces, or the biophysical properties of lipid bilayers. How these different hubs are spatiotemporally(More)
