Abstract
We show that several classes of insect non-LTR retrotransposons harbor self-cleaving ribozymes of the HDV family at their 5′ termini. In Drosophila the R2 ribozymes exhibit highly differential in vivo expression and robust in vitro activity, modulated by an upstream sequence originating from the insertion site. Our data suggest a role for self-cleaving ribozymes in co-transcriptional processing of retrotransposons with implications for downstream events, including translation and retrotransposition.
