Membrane targeting: getting Arl to the Golgi

Curr Biol. 2004 Jun 22;14(12):R483-5. doi: 10.1016/j.cub.2004.06.017.


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.
