Predicted to enable DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in positive regulation of chondrocyte differentiation and positive regulation of transcription by RNA polymerase II. Acts upstream of or within limb bud formation. Located in nucleus. Is expressed in several structures, including alimentary system; central nervous system; early conceptus; genitourinary system; and sensory organ. Orthologous to human ZNF219 (zinc finger protein 219). [provided by Alliance of Genome Resources, Apr 2022]
