Role of GTPases in ribosome assembly

Abstract

GTPases are a universally conserved class of regulatory proteins involved in such diverse cellular functions as signal transduction, translation, cytoskeleton formation, and intracellular transport. GTPases are also required for ribosome assembly in eukaryotes and bacteria, where they present themselves as possible regulatory molecules. Strikingly, in bacteria they represent the largest class of essential assembly factors. A review of their common structural, biochemical and genetic interactions is presented and integrated with models for their function in ribosome assembly. © 2007 Wiley Periodicals, Inc.
