Function

[NRD1_YEAST] Plays a role in sequence-specific regulation of nuclear pre-mRNA abundance. [SEN1_YEAST] ATP-dependent 5'->3' DNA/RNA helicase required for the expression and maturation of diverse classes of non-protein-coding RNAs like precursor tRNAs, rRNAs and small nuclear (snRNA) and nucleolar (snoRNA) RNAs. Directs RNA polymerase II transcription termination on snoRNAs as well as on several short protein-coding genes. May also play a role in transcription-coupled nucleotide excision repair.^{[1] [2] [3] [4] [5] [6]}
