Creative Proteomics offers high-quality myristoylation analysis services, including identification, quantification and characterization of protein myristoylation modifications, providing valuable insights into your protein research.
What is Myristoylation
Protein myristoylation is a crucial post-translational modification (PTM) that involves the covalent attachment of a myristoyl group—derived from myristic acid—to the N-terminal glycine residue of a protein. This modification is catalyzed by N-myristoyltransferase (NMT) enzymes and plays a pivotal role in modulating various cellular processes. Myristoylation facilitates the association of proteins with cellular membranes, influencing their localization, stability, and function.

The myristoyl group is a 14-carbon saturated fatty acid that confers hydrophobic properties on the modified protein. This hydrophobicity is instrumental in targeting proteins to cellular membranes, such as the plasma membrane or intracellular organelles. The myristoyl moiety inserts itself into the lipid bilayer, anchoring the protein and facilitating its interaction with membrane-bound components. Importantly, myristoylation is irreversible and occurs co-translationally, meaning it takes place during protein synthesis. The specificity of NMT for its substrates ensures precise regulation of myristoylation events within the cell.
