Predicted to enable DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Acts upstream of or within dosage compensation by inactivation of X chromosome; meiotic recombination checkpoint signaling; and spermatid development. Predicted to be located in nucleolus and nucleoplasm. Predicted to be active in nucleus. Is expressed in heart; liver; lung; metanephros; and reproductive system. Orthologous to human ZFY (zinc finger protein Y-linked). [provided by Alliance of Genome Resources, Apr 2022]
