ER-Golgi-localized proteins TMED2 and TMED10 control the formation of plasma membrane lipid nanodomains

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Oksana Andrei Sergeeva, Audrey Geneviève Chuat, Muhammad Umair Anwar, Giovanni D'Angelo, Laura Capolupo, Francisco De Magalhães Sarmento R De Mesquita, Triana Amen

To promote infections, pathogens exploit host cell machineries such as structural elements of the plasma membrane. Studying these interactions and identifying molecular players are ideal for gaining insights into the fundamental biology of the host cell. H ...

S-acylation controls SARS-CoV-2 membrane lipid organization and enhances infectivity

Béatrice Kunz, Didier Trono, Priscilla Turelli, Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Matteo Dal Peraro, Charlène Mireille Raymonde Raclot, Luciano Andres Abriata, Oksana Andrei Sergeeva, Giovanni D'Angelo, Francisco De Magalhães Sarmento R De Mesquita

SARS-CoV-2 virions are surrounded by a lipid bilayer that contains membrane proteins such as spike, responsible for target-cell binding and virus fusion. We found that during SARS-CoV-2 infection, spike becomes lipid modified, through the sequential action ...

Harnessing the Membrane Translocation Properties of AB Toxins for Therapeutic Applications

Françoise Gisou van der Goot Grunberg, Oksana Andrei Sergeeva

Over the last few decades, proteins and peptides have become increasingly more common as FDA-approved drugs, despite their inefficient delivery due to their inability to cross the plasma membrane. In this context, bacterial two-component systems, termed AB ...

Mammalian membrane trafficking as seen through the lens of bacterial toxins

Françoise Gisou van der Goot Grunberg, Oksana Andrei Sergeeva, Francisco De Magalhães Sarmento R De Mesquita

A fundamental question of eukaryotic cell biology is how membrane organelles are organised and interact with each other. Cell biologists address these questions by characterising the structural features of membrane compartments and the mechanisms that coor ...

Anthrax toxin requires ZDHHC5-mediated palmitoylation of its surface-processing host enzymes

Françoise Gisou van der Goot Grunberg, Oksana Andrei Sergeeva

The protein acyl transferase ZDHHC5 was recently proposed to regulate trafficking in the endocytic pathway. Therefore, we explored the function of this enzyme in controlling the action of bacterial toxins. We found that ZDHHC5 activity is required for two ...

Co-expression of CCT subunits hints at TRiC assembly

Oksana Andrei Sergeeva

The eukaryotic cytosolic chaperonin, t-complex polypeptide 1 (TCP-1) ring complex or TRiC, is responsible for folding a tenth of the proteins in the cell. TRiC is a double-ringed barrel with each ring composed of eight different CCT (chaperonin containing ...

Kicking Out Pathogens in Exosomes

Françoise Gisou van der Goot Grunberg, Oksana Andrei Sergeeva

Host-pathogen interactions involve a series of attacks and counter-attacks. Miao et al. show that, although some invading bacteria can take shelter in lysosomes by neutralizing their pH, this respite is temporary, as host cells can expel them in exosomes. ...
