Setty SR, et al. (2004) Golgi targeting of ARF-like GTPase Arl3p requires its Nalpha-acetylation and the integral membrane protein Sys1p. Nat Cell Biol 6(5):414-9
Abstract: Myristoylation of ARF family GTPases is required for their association with Golgi and endosomal membranes, where they regulate protein sorting and the lipid composition of these organelles. The Golgi-localized ARF-like GTPase Arl3p/ARP lacks a myristoylation signal, indicating that its targeting mechanism is distinct from myristoylated ARFs. We demonstrate that acetylation of the N-terminal methionine of Arl3p requires the NatC N(alpha)-acetyltransferase and that this modification is required for its Golgi localization. Chemical crosslinking and fluorescence microscopy experiments demonstrate that localization of Arl3p also requires Sys1p, a Golgi-localized integral membrane protein, which may serve as a receptor for acetylated Arl3p.
