Predicted to enable RNA polymerase I general transcription initiation factor binding activity. Predicted to be involved in RNA polymerase I preinitiation complex assembly; nucleolar large rRNA transcription by RNA polymerase I; and transcription elongation from RNA polymerase I promoter. Predicted to be located in fibrillar center and nucleoplasm. Predicted to be part of RNA polymerase I complex. Orthologous to human POLR1E (RNA polymerase I subunit E).
