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 ...

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 ...
