Mechanisms and functions of protein S-acylation

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Francisco De Magalhães Sarmento R De Mesquita

Over the past two decades, protein S-acylation (often referred to as S-palmitoylation) has emerged as an important regulator of vital signalling pathways. S-Acylation is a reversible post-translational modification that involves the attachment of a fatty a ...

Inhibitors of acyl protein thioesterases against microbial infections

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Valeria Cagno, Francisco De Magalhães Sarmento R De Mesquita

The present invention relates inhibitors of acyl protein thioesterases and method of preparation thereof. It also relates to the use of inhibitors of acyl protein thioesterases in the treatment and/or prevention of a microbial infection such as viral or ba ...

SARS-CoV-2 hijacks a cell damage response, which induces transcription of a more efficient Spike S-acyltransferase

Béatrice Kunz, Didier Trono, Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Audrey Geneviève Chuat, Francisco De Magalhães Sarmento R De Mesquita, Lucie Josepha Marie Bracq, Joana Carlevaro Fita, Nattawadee Panyain

SARS-CoV-2 infection requires Spike protein-mediated fusion between the viral and cellular membranes. The fusogenic activity of Spike depends on its post-translational lipid modification by host S-acyltransferases, predominantly ZDHHC20. Previous observati ...

S-acylation: an orchestrator of the life cycle and function of membrane proteins

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Francisco De Magalhães Sarmento R De Mesquita

S-acylation is a covalent post-translational modification of proteins with fatty acids, achieved by enzymatic attachment via a labile thioester bond. This modification allows for dynamic control of protein properties and functions in association with cell ...

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 ...

Meeting report - Cell dynamics: host-pathogen interface

Francisco De Magalhães Sarmento R De Mesquita

Two years into the most significant infectious disease event of our generation, infections have populated every conversation and in-depth understanding of host-pathogen interactions has, perhaps, never been more important. In a successful return to in-pers ...

Palmitoylated acyl protein thioesterase APT2 deforms membranes to extract substrate acyl chains

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Patrick Alain Sandoz, Florence Pojer, Matteo Dal Peraro, Sylvia Ho, Martina Audagnotto, Giulia Fonti, Maria Josefina Marcaida Lopez, Muhammad Umair Anwar, Francisco De Magalhães Sarmento R De Mesquita

Acyl protein thioesterase APT2 interacts with membranes via its charged beta-tongue, becomes palmitoylated by ZDHHC3/7 and deforms the bilayer to extract substrate acyl chains. APT2 deacylation leads to its membrane release and degradation. ...

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 ...

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 ...

Mechanisms protecting host cells against bacterial pore-forming toxins

Francisco De Magalhães Sarmento R De Mesquita

Pore-forming toxins (PFTs) are key virulence determinants produced and secreted by a variety of human bacterial pathogens. They disrupt the plasma membrane (PM) by generating stable protein pores, which allow uncontrolled exchanges between the extracellula ...
