U6 snRNA phosphodiesterase 1

UniProtKB accession:  Q9BQ65

Grouped By:  Matching UniProtKB accession

UniProtKB description:  3'-5' RNA exonuclease that trims the 3' end of oligo(U) and oligo(A) tracts of the pre-U6 small nuclear RNA (snRNA) molecule, leading to the formation of a mature U6 snRNA 3' end-terminated with a 2',3'-cyclic phosphate (PubMed:23022480, PubMed:22899009, PubMed:26213367, PubMed:31832688, PubMed:23190533, PubMed:28887445, PubMed:30215753). Participates in the U6 snRNA 3' end processing that prevents U6 snRNA degradation (PubMed:23022480, PubMed:22899009, PubMed:26213367, PubMed:31832688, PubMed:23190533, PubMed:28887445, PubMed:30215753). In addition also removes uridines from the 3' end of U6atac snRNA and possibly the vault RNA VTRNA1-1 (PubMed:26213367).
