Automated description from the Alliance of Genome Resources (Release 3.2)
Predicted to have RNA polymerase I core promoter sequence-specific DNA binding activity. Predicted to be involved in RNA polymerase I preinitiation complex assembly and nucleolar large rRNA transcription by RNA polymerase I. Predicted to localize to RNA polymerase I core factor complex; RNA polymerase transcription factor SL1 complex; and nucleoplasm. Is expressed in heart and limb. Orthologous to human TAF1B (TATA-box binding protein associated factor, RNA polymerase I subunit B).
