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 ...

Dynamics of CLIMP-63 S-acylation control ER morphology

Vassily Hatzimanikatis, Françoise Gisou van der Goot Grunberg, Graham Knott, Kathryn Hess Bellwald, Laurence Gouzi Abrami, Béatrice Kunz, Luciano Andres Abriata, Sylvia Ho, Catherine Maclachlan, Patrick Alain Sandoz

A key player in the formation of endoplasmic reticulum sheets is CLIMP-63, but mechanistic details remained elusive. Here authors combined cellular experiments and mathematical modelling to show that S-acylation of CLIMP-63 regulates its function by mediat ...

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

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

Local and substrate-specific S-palmitoylation determines subcellular localization of G alpha o

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

Peripheral membrane proteins (PMPs) associate with cellular membranes through post-translational modifications like S-palmitoylation. The Golgi apparatus is generally viewed as the transitory station where palmitoyl acyltransferases (PATs) modify PMPs, whi ...

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

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

Transposon-activated POU5F1B promotes colorectal cancer growth and metastasis

Didier Trono, Laurence Gouzi Abrami, Sandra Eloise Kjeldsen, Evaristo Jose Planet Letschert, Julien Léonard Duc, Laia Simo Riudalbas, Alexandre Coudray, Sagane Dind

The treatment of colorectal cancer (CRC) is an unmet medical need in absence of early diagnosis. Here, upon characterizing cancer-specific transposable element-driven transpochimeric gene transcripts (TcGTs) produced by this tumor in the SYSCOL cohort, we ...
