Palmitoylation mediates membrane association of hepatitis E virus ORF3 protein and is required for infectious particle secretion

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

Hepatitis E virus (HEV) is a positive-strand RNA virus encoding 3 open reading frames (ORF). HEV ORF3 protein is a small, hitherto poorly characterized protein involved in viral particle secretion and possibly other functions. Here, we show that HEV ORF3 p ...

Mechanisms and functions of protein S-acylation

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Francisco De Magalhães Sarmento Ribeiro 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 ...

Hyaline Fibromatosis Syndrome inducing mutations in the ectodomain of anthrax toxin receptor 2 can be rescued by proteasome inhibitors

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Nicolas Jean Philippe Guex, Julie Deuquet Ariosa

Hyaline Fibromatosis Syndrome (HIS) is a human genetic disease caused by mutations in the anthrax toxin receptor 2 (or cmg2) gene, which encodes a membrane protein thought to be involved in the homeostasis of the extracellular matrix. Little is known about ...

S-acylation by ZDHHC20 targets ORAI1 channels to lipid rafts for efficient Ca2+ signaling by Jurkat T cell receptors at the immune synapse

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

Efficient immune responses require Ca2+ fluxes across ORAI1 channels during engagement of T cell receptors (TCR) at the immune synapse (IS) between T cells and antigen presenting cells. Here, we show that ZDHHC20-mediated S-acylation of the ORAI1 channel a ...

Akt Is S-Palmitoylated: A New Layer of Regulation for Akt

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

The protein kinase Akt/PKB participates in a great variety of processes, including translation, cell proliferation and survival, as well as malignant transformation and viral infection. In the last few years, novel Akt posttranslational modifications have ...

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

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

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 ...

Anthrax toxin receptor 2a controls mitotic spindle positioning

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

Oriented mitosis is essential during tissue morphogenesis. The Wnt/planar cell polarity (Wnt/PCP) pathway orients mitosis in a number of developmental systems, including dorsal epiblast cell divisions along the animal-vegetal (A-V) axis during zebrafish ga ...

Hemagglutinin of Influenza A, but not of Influenza B and C viruses is acylated by ZDHHC2, 8, 15 and 20

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

Hemagglutinin (HA), a glycoprotein of Influenza A viruses and its proton channel M2 are site-specifically modified with fatty acids. Whereas two cysteines in the short cytoplasmic tail of HA contain only palmitate, stearate is exclusively attached to one c ...

CMG2/ANTXR2 regulates extracellular collagen VI which accumulates in hyaline fibromatosis syndrome

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Alessandra Piersigilli, Béatrice Kunz, Jérôme Bürgi, Julie Deuquet Ariosa

Loss-of-function mutations in capillary morphogenesis gene 2 (CMG2/ANTXR2), a transmembrane surface protein, cause hyaline fibromatosis syndrome (HFS), a severe genetic disorder that is characterized by large subcutaneous nodules, gingival hypertrophy and ...

Hijacking Multivesicular Bodies Enables Long-Term and Exosome-Mediated Long-Distance Action of Anthrax Toxin

Lucia Brandi, Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

Anthrax lethal toxin is a classical AB toxin comprised of two components: protective antigen (PA) and lethal factor (LF). Here, we show that following assembly and endocytosis, PA forms a channel that translocates LF, not only into the cytosol, but also in ...

Model-Driven Understanding of Palmitoylation Dynamics: Regulated Acylation of the Endoplasmic Reticulum Chaperone Calnexin

Vassily Hatzimanikatis, Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami, Patrick Alain Sandoz, Georgios Savoglidis, Tiziano Dallavilla

Cellular functions are largely regulated by reversible post-translational modifications of proteins which act as switches. Amongst these, S-palmitoylation is unique in that it confers hydrophobicity. Due to technical difficulties, the understanding of this ...
