Enables DNA binding activity. Involved in positive regulation of gene expression. Acts upstream of or within several processes, including branching involved in mammary gland duct morphogenesis; motor neuron axon guidance; and negative regulation of mammary gland epithelial cell proliferation. Located in nucleus. Is expressed in several structures, including alimentary system; central nervous system; embryo mesenchyme; sensory organ; and urinary system.
