Membrane targeting: getting Arl to the Golgi.
Post-translational modification with myristoyl or prenyl groups is essential for membrane association of many small GTPases in the Ras superfamily. Two recent papers show that, rather than myristoylation, amino-terminal acetylation of the Arf-like protein Arl3p is required for Golgi targeting via an interaction with an integral membrane protein called Sys1.
