The double-stranded-RNA-binding motif: Interference and much more

Abstract

RNA duplexes have been catapulted into the spotlight by the discovery of RNA interference and related phenomena. But double-stranded and highly structured RNAs have long been recognized as key players in cell processes ranging from RNA maturation and localization to the antiviral response in higher organisms. Penetrating insights into the metabolism and functions of such RNAs have come from the identification and study of proteins that contain the double-stranded-RNA-binding motif.
