WebFeb 11, 2024 · N-myristoylation on glycine is an irreversible modification that has long been recognized to govern protein localization and function.In contrast, the biological roles of lysine myristoylation remain ill-defined. We demonstrate that the cytoplasmic scaffolding protein, gravin-α/A kinase–anchoring protein 12, is myristoylated on two lysine residues … Myristoylation not only diversifies the function of a protein, but also adds layers of regulation to it. One of the most common functions of the myristoyl group is in membrane association and cellular localization of the modified protein. Though the myristoyl group is added onto the end of the protein, in some cases it is sequestered within hydrophobic regions of the protein rather than solvent expo…
