Systematic name YLR430W
Gene name SEN1
Aliases CIK3, NRD2
Feature type ORF, Verified
Coordinates Chr XII:993434..1000129
Primary SGDID S000004422


Description of YLR430W: Presumed helicase and subunit of the Nrd1 complex (Nrd1p-Nab3p-Sen1p); complex interacts with the exosome to mediate 3' end formation of some mRNAs, snRNAs, snoRNAs, and CUTs; homolog of Senataxin which causes Ataxia-Oculomotor Apraxia 2 and a dominant form of amyotrophic lateral sclerosis[1][2][3][4][5]
