Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; chromatin binding activity; and histone deacetylase binding activity. Involved in negative regulation of DNA-binding transcription factor activity and negative regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including alimentary system; genitourinary system; hemolymphoid system; skeleton; and skin. Orthologous to human ZNF101 (zinc finger protein 101).
