RNA aptamers as effective protein antagonists in a multicellular organism.

Abstract excerpt

RNA aptamers selected against proteins can be used to modulate specific protein function. Expression of such reagents in cells and whole organisms could provide a means of dissecting and controlling molecular mechanisms in vivo. We demonstrate that Drosophila B52 protein can be specifically inhibited in vitro and in vivo by a multivalent RNA aptamer. This inhibitory aptamer RNA binds B52 avidly and inhibits...
