[https://www.uniprot.org/uniprot/SEN1_YEAST 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.<ref>PMID:11565036</ref> <ref>PMID:15121901</ref> <ref>PMID:17157256</ref> <ref>PMID:8943355</ref> <ref>PMID:9365256</ref> <ref>PMID:9819377</ref>

== Publication Abstract from PubMed ==
 +
The Nrd1-Nab3-Sen1 (NNS) complex carries out the transcription termination of non-coding RNAs (ncRNAs) by RNA polymerase II (Pol II) in yeast, although the detailed interactions among its subunits remain obscure. Here we have identified three sequence motifs in Sen1 that mediate direct interactions with the Pol II CTD interaction domain (CID) of Nrd1, determined the crystal structures of these Nrd1 interaction motifs (NIMs) bound to the CID, and characterized the interactions in vitro and in yeast. Removal of all three NIMs abolishes NNS complex formation and gives rise to ncRNA termination defects.
