mRNA-type introns in U6 small nuclear RNA genes: implications for the catalysis in pre-mRNA splicing.

abstract：:Export to the cytoplasm of U3 RNA transcribed from a rat U3 gene injected into the nucleus of Xenopus oocytes indicates that the biogenesis of U3 RNA, like that of the previously studied Sm-precipitable nucleoplasmic snRNAs (U1, U2, U4, and U5), includes a cytoplasmic phase. The regulation of import of the U3 snRNA in...
