Automated description from the Alliance of Genome Resources
Contributes to DNA-binding transcription repressor activity, RNA polymerase II-specific and RNA polymerase II regulatory region sequence-specific DNA binding activity. Involved in negative regulation of transcription by RNA polymerase II. Localizes to the RNA polymerase II transcription factor complex. Is expressed in several structures, including craniocervical region bone; limb mesenchyme; neural tube; oocyte; and rib. Orthologous to human MXD4 (MAX dimerization protein 4).
