Protein S-palmitoylation (null)

Protein S-palmitoylation is a reversible lipid modification in which a palmitoyl group is attached to the sulfur atom of cysteine residues in target proteins via a thioester bond. This modification is catalyzed by DHHC-family palmitoyltransferases and reversed by acyl-protein thioesterases. S-palmitoylation regulates diverse protein functions, including membrane association, stability, localization, trafficking, and protein-protein interactions. It is essential in processes such as signal transduction, immune response, and synaptic function. Dysregulation of protein S-palmitoylation is implicated in numerous pathological conditions, notably cancer, neurodegenerative, cardiovascular, and immune-mediated diseases. Pharmacological modulation of S-palmitoylation is an emerging area in therapeutic development, though non-specificity and safety remain major challenges
