STAR, a gene family involved in signal transduction and activation of RNA

Abstract

A new subfamily of KH-domain-containing RNA-binding proteins is encoded by genes that are conserved from yeast to humans. Mutations with interesting developmental phenotypes have been identified in Caenorhabditis elegans, Drosophila and mouse. It is hypothesized that these bifunctional proteins provide a rich source of interesting molecular information about development and define a new cellular pathway that links signal transduction directly to RNA metabolism.
