Protein lipid modifications in signaling and subcellular targeting.

Classically perceived as means for recruiting proteins to the membranes, protein lipid modifications are known today to play diverse roles in subcellular targeting, protein-protein interactions and signaling. This review focuses on three protein lipid modifications: prenylation, S-acylation and N-myristoylation and attempts to provide an up-to-date view of their function by focusing on several model proteins.
