Enables DNA binding activity. Acts upstream of or within several processes, including hormone-mediated signaling pathway; nervous system development; and reproductive structure development. Located in cytoplasm and nucleus. Is expressed in several structures, including central nervous system; genitourinary system; heart mesentery; limb segment; and mammary gland primordium. Human ortholog(s) of this gene implicated in several diseases, including artery disease (multiple); autoimmune disease (multiple); hypospadias; neurodegenerative disease (multiple); and ovarian dysgenesis 8.
