During the last years, post-translational modification of peripheral membrane proteins with hydrophobic side groups has been attributed to a couple of additional functions than just simple anchoring into lipid bilayers. In particular isoprenylation and N- and S-acylation did quicken interest in terms of specific recognition elements for protein-protein interactions and as hydrophobic switches that allow for temporal regulated association with distinct target structures. Furthermore new insights into the heterogeneity of natural membranes have connected the physical properties of e.g. farnesyl or palmitoyl side chains with a preference for such sub-compartments as lipid rafts or caveolae. In this review the impact of the two frequently realized modifications by isoprenylation and S-acylation on the process of cellular signal transduction is exemplified with proteins of the Ras and Rab family of small GTP-binding proteins.
