Site-Specific Modification of Pre-mRNA: the 2′-Hydroxyl Groups at the Splice Sites

Moore, Melissa J., Sharp, Phillip A.·1992·Science

Abstract

A simple and efficient method for synthesizing long, site-specifically modified RNA molecules was developed whereby segments of RNA were joined with the use of bacteriophage T4 DNA ligase. A single hydrogen or O -methyl group was substituted for the 2′-hydroxyl group at either splice site of a nuclear pre-messenger RNA substrate. Splicing of the modified pre-messenger RNA's in vitro revealed that, although a 2′-hydroxyl is not absolutely required at either splice site, the 2′-hydroxyl at the 3′ splice site is important for the second step of splicing. These results are compared to previous studies of analogous 2′-hydroxyl groups in the self-splicing Tetrahymena group I intron.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
