Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and enzyme binding activity. Involved in brain development; regulation of cell cycle; and regulation of neuron differentiation. Located in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in prostate cancer. Orthologous to human ZFHX3 (zinc finger homeobox 3). [provided by Alliance of Genome Resources, Apr 2022]
