Ribozyme-mediated trans insertion-splicing into target RNAs

Abstract

The trans insertion-splicing (TIS) reaction is a technique that can be used to site-specifically insert an RNA donor substrate into a separate RNA acceptor substrate. The TIS reaction, which is catalyzed by a group I intron-derived ribozyme from Pneumocystis carinii, is described with regards to system design, ribozyme preparation, and the overall protocol for conducting the TIS reaction. © 2012 Springer Science+Business Media, LLC.
