U4 small nuclear RNA pseudogenes from rat genome have common truncated 3'-ends.
Four U4 RNA pseudogenes were isolated and characterized from a rat genomic bank. The four pseudogenes contained sequences completely homologous to U4 RNA from nucleotides 1 to 67 and had common truncated 3'-ends. Three of the four pseudogenes were flanked by 14 to 18 nucleotide-long direct repeats. The structural features of these four U4 RNA pseudogenes are consistent with the hypothesis that these pseudogenes arose by RNA self-primed complementary DNA synthesis and integration into the genome (Van Arsdell et al., Cell 26:11-17, 1981).
