Webb20 maj 2013 · Summary. Attachment of lipophilic groups is a widespread modification that occurs on nearly 1,000 proteins of diverse structure and function. At least five different types of lipids can be covalently attached to proteins: fatty acids, isoprenoids, sterols, phospholipids, and glycosylphosphatidyl inositol (GPI) anchors. Webb18 sep. 2024 · Proteins are modified by fatty acid on the cysteine residue which induces a hydrophobic interactions. This is a very important post translation modification of proteins that diversifies proteins by enabling protein protein interactions, signal transduction and many other protein functions.

WebbMost eukaryotic proteins are post-translationally modified, and modification has profound effects on protein function. One key modification is the attachment of a lipid group to certain amino acids; this typically facilitates subcellular targeting (association with a membrane) and protein–protein interactions (by virtue of the large hydrophobic moiety).
