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 ...

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, 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 ...

Transposon-activated POU5F1B promotes colorectal cancer growth and metastasis

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

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 ...

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 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 ...
