Publication Abstract from PubMed
Rho-proteins are small GTP/GDP-binding proteins primarily involved in cytoskeleton regulation. Their GTP/GDP-cycle is often tightly connected to a membrane/cytosol-cycle regulated by the Rho guanine nucleotide dissociation inhibitor alpha (RhoGDIalpha). RhoGDIalpha has been regarded as a housekeeping regulator essential to control homeostasis of Rho-proteins. Recent proteomic screens showed that RhoGDIalpha is extensively lysine acetylated. Here, we present the first comprehensive structural and mechanistic study to show how RhoGDIalpha function is regulated by lysine acetylation. We discover that lysine acetylation impairs Rho-protein binding and increases GEF-catalysed nucleotide exchange on RhoA, being prerequisites to constitute a bona fide GDI-displacement factor. RhoGDIalpha-acetylation interferes with Rho-signalling resulting in alteration of cellular filamentous actin. Finally, we discover that RhoGDIalpha is endogenously acetylated in mammalian cells, we identify CBP, p300, pCAF as RhoGDIalpha-acetyltransferases and Sirt2, HDAC6 as specific deacetylases, showing the biological significance of this post-translational modification.
