The hemagglutinin of influenza virus is palmitoylated with long-chain fatty acids.
Palmitoylation of HA is believed to occur in the cis golgi network (Veit 1993), shortly after trimerisation of the molecule, and before cleavage of the HA into HA1 and HA2. HA is palmitoylated through thioester linkages at three cysteine residues located in the cytoplasmic domain and at the carboxy-terminal end of the transmembrane region. Lack of acylation has no obvious influence on the biological activities of HA.
