Predicted to enable RNA polymerase III general transcription initiation factor activity and RNA polymerase III type 3 promoter sequence-specific DNA binding activity. Acts upstream of or within regulation of mRNA stability. Predicted to be part of transcription factor TFIIIB complex and transcription preinitiation complex. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in cerebellofaciodental syndrome. Orthologous to human BRF1 (BRF1 RNA polymerase III transcription initiation factor subunit).
