Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and methyl-CpG binding activity. Involved in prostate gland development and response to testosterone. Predicted to be located in nucleoplasm. Predicted to be part of transcription regulator complex. Human ortholog(s) of this gene implicated in ductal carcinoma in situ and renal cell carcinoma. Orthologous to human HOXB13 (homeobox B13). [provided by Alliance of Genome Resources, Apr 2022]
