Recognizes the ribosomal RNA gene promoter and activates transcription mediated by RNA polymerase I through cooperative interactions with the transcription factor SL1/TIF-IB complex. It binds specifically to the upstream control element. Source: Recombinant protein corresponding to aa1-764 from human Nucleolar transcription factor 1, fused to 6X His-Tag at N-terminal, expressed in E. coli.
