Enables RNA polymerase I cis-regulatory region sequence-specific DNA binding activity and RNA polymerase I general transcription initiation factor activity. Involved in chromatin organization and nucleolar large rRNA transcription by RNA polymerase I. Located in nucleolus. Part of RNA polymerase I upstream activating factor complex.
SGD Description
Subunit of UAF (upstream activation factor) complex; UAF is an RNA polymerase I specific transcription stimulatory factor composed of Uaf30p, Rrn5p, Rrn9p, Rrn10p, histones H3 and H4; targeting factor for the UAF that facilitates activation of many rDNA genes; deletion decreases cellular growth rate; UAF30 has a paralog, TRI1, that arose from the whole genome duplication
