Enables RNA binding activity; RNA polymerase binding activity; and chromatin binding activity. Acts upstream of or within RNA processing; pericentric heterochromatin organization; and regulation of chromosome organization. Located in chromosome, centromeric region. Is expressed in brain ventricular layer; inferior colliculus; submandibular gland primordium; and thymus primordium. Orthologous to human WDHD1 (WD repeat and HMG-box DNA binding protein 1).
