Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in immune system process and regulation of transcription by RNA polymerase II. Predicted to be located in cytosol. Predicted to be active in nucleus. Biomarker of acute pancreatitis and familial hyperlipidemia. Human ortholog(s) of this gene implicated in immunodeficiency 65. Orthologous to human IRF9 (interferon regulatory factor 9).
