Predicted to enable histone deacetylase binding activity. Predicted to contribute to DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Predicted to be involved in regulation of transcription by RNA polymerase II. Predicted to act upstream of or within Ras protein signal transduction and positive regulation of transcription by RNA polymerase II. Predicted to be located in cytosol; intercellular bridge; and nucleoplasm. Predicted to be part of RNA polymerase II transcription regulator complex. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in MHC class II deficiency and severe combined immunodeficiency. Orthologous to human RFXANK (regulatory factor X associated ankyrin containing protein).
