DNA-binding protein that recognizes sequence-specific replication termini (Ter sites) within rDNA (PubMed:14576157). Binds to rDNA terminator elements and mediates efficient RNA polymerase I transcription termination (PubMed:22805593). Required for rDNA silencing at the non-transcribed spacer 1 (NTS1). Promotes the association of SIR2 with NTS1 and contributes to maintenance of rDNA stability (PubMed:22362748). Interacts with FOB1 (PubMed:14576157, PubMed:22362748). Interacts with the RENT complex subunits NET1 and SIR2 (PubMed:22362748). Decreases the association of SIR2 with NTS1, decreases rDNA stability and shortens replicative lifespan. Present with 432 molecules/cell in log phase SD medium.
