WebMany small nuclear RNAs, such as U snRNAs, are involved in mediating or regulating posttranslational RNA-processing events such as splicing. Most of these RNAs are transcribed in the nucleus by Pol II or Pol III as pre-snRNA, then capped on the 5′ end and exported to the cytoplasm. WebEukaryotic cells contain a large number of U small nuclear RNAs (U-snRNAs) involved in various RNA processing reactions in the nucleoplasm and nucleous. Most of the U-snRNAs have 5'-terminal caps added to the end of the primary transcript. Here we describe two variants of a snRNA, called U17, identified in human HeLa cells.
