Résumé
U5 snRNAs in trypanosomatid protozoa do not contain the trimethylguanosine cap structures that are often targeted in snRNA isolation procedures. As a result, the trypanosomatids are not well represented in the database of available U5 snRNA sequences. We have isolated and determined the sequence of the U5 snRNA from Crithidia fasciculata. Comparison with previously published trypanosomatid U5 snRNA sequences allows us to deduce the pattern of structural conservation and variation among these very divergent snRNA molecules.
