title: GEFs, GAPs, GDIs and effectors: taking a closer (3D) look at the regulation of Ras-related GTP-binding proteins.
abstract: Cell biology depends on the interactions of macromolecules, such as protein-DNA, protein-protein or protein-nucleotide interactions. GTP-binding proteins are no exception to the rule. They regulate cellular processes as diverse as protein biosynthesis and intracellular membrane trafficking. Recently, a large number of genes encoding GTP-binding proteins and the proteins that interact with these molecular switches have been cloned and expressed. The 3D structures of some of these have also been elucidated.
