Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Predicted to be involved in negative regulation of transcription by RNA polymerase II. Predicted to act upstream of or within cell aging. Predicted to be located in mitochondrion and nuclear speck. Predicted to be part of histone deacetylase complex. Predicted to be active in nucleus. Is expressed in genitourinary system; paraxial mesenchyme; and tail. Orthologous to human ZNF217 (zinc finger protein 217). [provided by Alliance of Genome Resources, Apr 2022]
