The nematode Caenorhabditis elegans has an unusual small nuclear RNA, containing a 100-nucleotide RNA molecule, spliced leader RNA, which donates its 5' 22 nucleotides to a variety of recipient RNAs by a trans-splicing reaction. The spliced leader RNA has a 5' trimethylguanosine (TMG) cap, which becomes the 5' end of trans-spliced mRNAs. We found that mature trans-spliced mRNAs were immunoprecipitable with anti-TMG cap antibodies and that TMG-containing dinucleotides specifically competed with… CONTINUE READING
