A mouse U3 RNA pseudogene has been identified; it corresponds to a U3B full length coding sequence with a 3'-oligo(A) tail, precisely flanked at both ends by a pair of 15 bp direct repeats. These structural features suggest that it has arisen through an RNA-mediated mechanism involving an insertion at staggered nicks in the genome. Sequence data indicate that this mouse specimen has been generated by a different event as compared to the recently described rat pseudogenes. It represents the first reported case, for a pseudogene of this class, to be present at more than one copy per genome.
