Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in positive regulation of transcription by RNA polymerase II. Predicted to be located in cytosol and nucleoplasm. Predicted to be active in nucleus. Is expressed in several structures, including central nervous system; early conceptus; genitourinary system; limb; and retina. Orthologous to human DMTF1 (cyclin D binding myb like transcription factor 1). [provided by Alliance of Genome Resources, Apr 2022]
