At the Research Frontiers of Small GTPases

Abstract

Small GTPases act as molecular switches in regulating a myriad of cellular signaling, cytoskeletal dynamics, vesicular trafficking, and membrane/organelle transport processes. Here, I provide an editorial overview of papers collected in this Special Issue on the “Regulation and Function of Small GTPases 2.0”.
