Summary: Enables RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including Sertoli cell development; diencephalon development; and face development. Acts upstream of or within animal organ morphogenesis; forebrain development; and spermatid differentiation. Predicted to be located in nucleoplasm. Predicted to be active in nucleus. Is expressed in several structures, including brain; branchial arch; early conceptus; embryo ectoderm; and gonad. Used to study hydrocephalus. Human ortholog(s) of this gene implicated in X-linked panhypopituitarism. Orthologous to human SOX3 (SRY-box transcription factor 3). [provided by Alliance of Genome Resources, Dec 2024]

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
