Automated description from the Alliance of Genome Resources (Release 7.0.0)
Contributes to DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in negative regulation of transcription by RNA polymerase II. Acts upstream of or within negative regulation of DNA-templated transcription. Part of RNA polymerase II transcription regulator complex. Is expressed in several structures, including craniocervical region bone; limb mesenchyme; neural tube; skin; and thymus. Orthologous to human MXD4 (MAX dimerization protein 4).
