S-palmitoylation, in its most specific sense, refers to the process whereby a peptide is modified by the formation of a thioester linkage between palmitic acid and a cysteine moiety on the native chain. S-palmitoylation can also refer to the general process of protein acylation by fatty acids.
Additional recommended knowledge
Because S-palmitoylation is a dynamic, post-translational process, it is believed to be employed by the cell to alter the subcellular localization, protein-protein interactions, or binding capacities of a protein.
The palmitoylation cycles of a wide array of enzymes have been characterized in the past few years, including H-Ras, Gsα, the β2-adrenergic receptor, and endothelial nitric oxide synthase (eNOS).
