Identification and sequencing of two isopentenyladenosine-modified transfer RNAs from Chinese hamster ovary cells.

To determine the presence and identity of isopentenyladenosine-containing transfer RNAs (tRNAs) in a mammalian cell line, we adopted a novel method to isolate, clone and sequence these RNAs. This method was based on 3' polyadenylation of the tRNA prior to cDNA synthesis, PCR amplification, cloning and DNA sequencing. Using this unique procedure, we report the cloning and sequencing of the selenocysteine-tRNA and mitochondrial tryptophan-tRNA from Chinese hamster ovary cells which contain this specific tRNA modification. This new method will be useful in the identification of other tRNAs and other small RNAs where the primary sequence is unknown.[1]
