Many proteins are post-translationally modified by lipid moieties such as palmitoyl or prenyl (e.g., farnesyl) groups, creating functional proteolipids. Lipid modifications share the property of increasing a protein's hydrophobicity and thus the propensity of that protein to associate with a membrane. These modifications are used to control the localization and activity of membrane-associated proteins. A well-recognized paradigm is farnesylation of the Ras GTPase that helps target this critical signaling protein to the plasma membrane.
