Palmitoylation is a process in which a fatty acid called palmitate is attached to a protein. This process is essential for regulating protein localization and function in cells. Synonyms for palmitoylation include S-palmitoylation, protein palmitoylation, lipidation, and acylation. These terms all refer to the same process of adding a lipid molecule, such as palmitate, to a protein. Palmitoylation plays an important role in a variety of cellular processes, including signal transduction, membrane trafficking, and protein-protein interactions. Understanding the various synonyms for palmitoylation can help researchers better understand and communicate about this important biological process.
