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 contribute to DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in regulation of transcription, DNA-templated. Located in cytoplasm and nucleus. Used to study breast adenocarcinoma and esophageal cancer. Human ortholog(s) of this gene implicated in neurofibrosarcoma and prostate cancer. Orthologous to human MXI1 (MAX interactor 1, dimerization protein).
