Enables DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and protein homodimerization activity. Involved in positive regulation of transcription by RNA polymerase II. Acts upstream of or within gamete generation and negative regulation of transcription by RNA polymerase II. Part of transcription regulator complex. Is expressed in several structures, including early conceptus; embryo ectoderm; genitourinary system; nervous system; and retina. Orthologous to human NR6A1 (nuclear receptor subfamily 6 group A member 1). [provided by Alliance of Genome Resources, Apr 2022]
