Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in positive regulation of transcription by RNA polymerase II. Predicted to be located in cytoplasm; fibrillar center; 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 Vulto-van Silfout-de Vries syndrome. Orthologous to human DEAF1 (DEAF1 transcription factor). [provided by Alliance of Genome Resources, Apr 2022]
