Trans-splicing of a Mutated Glycosylasparaginase Mrna Sequence by a Group I Ribozyme Deficient in Hydrolysis

Authors: Eirik W. Lundblad, Peik Haugen, and Steinar D. Johansen

Field: Molecular Biotechnology, RNA Research, Fisheries and Natural Sciences

Document Summary: This research investigates the application of a modified group I ribozyme, DiGIR2AP9.2, for RNA reprogramming through trans-splicing. The original DiGIR2 ribozyme, derived from a mobile group I intron, was altered by deleting a structural element in its P9 domain. This modification effectively eliminates hydrolytic side reactions at the 3′ splice site without compromising self-splicing efficiency. The study demonstrates that this modified ribozyme catalyzes both cis-splicing and trans-splicing of a human glycosylasparaginase mRNA sequence with efficiency comparable to the original DiGIR2 ribozyme, but with significantly reduced unwanted hydrolysis. This development offers a potentially improved tool for RNA reprogramming, addressing the challenge of inefficiency in cellular contexts and the issue of competing side reactions that can lower overall splicing efficacy.
