Abstract

Using systematic evolution of ligands by exponential enrichment (SELEX), an RNA molecule was isolated that displays a 1,000-fold higher affinity for guanosine residues that carry an N-7 methyl group than for nonmethylated guanosine residues. The methylated guanosine residue closely resembles the 5′ terminal cap structure present on all eukaryotic mRNA molecules. The cap-binding RNA specifically inhibited the translation of capped but not uncapped mRNA molecules in cell-free lysates prepared from either human HeLa cells or from Saccharomyces cerevisiae . These findings indicate that the cap-binding RNA will also be useful in studies of other cap-dependent processes such as pre-mRNA splicing and nucleocytoplasmic mRNA transport.
