Myristoylation and palmitoylation are commonly coupled modifications. Myristoylation alone can promote transient membrane interactions [5] that enable proteins to anchor to membranes but dissociate easily. Further palmitoylation allows for tighter anchoring and slower dissociation from membranes when required by the cell.
Palmitoylation also appears to play a significant role in subcellular trafficking of proteins between membrane compartments, [3] as well as in modulating protein–protein interactions. [4] In contrast to prenylation and myristoylation, palmitoylation is usually reversible (because the bond between palmitic acid and protein is often a thioester ...
Palmitoylation. S-palmitoylation (i.e. attachment of palmitic acid) is a reversible protein modification in which a palmitic acid is attached to a specific cysteine residue via thioester linkage. [2] [11] The term S-acylation can also be used when other medium and long fatty acids chains are also attached to palmitoylated proteins.

In signal transduction via G protein, palmitoylation of the α subunit, prenylation of the γ subunit, and myristoylation is involved in tethering the G protein to the inner surface of the plasma membrane so that the G protein can interact with its receptor. [10]

The processes are respectively named myristoylation (usually at N-terminal Gly), palmitoylation (to cysteine), and prenylation (also to cysteine). Despite the seemingly specific names, N-myristoylation and S-palmitoylation can also involve some other fatty acids, most commonly in plants and viral proteolipids.
