Enables DNA-binding transcription factor activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and histone deacetylase binding activity. Involved in positive regulation of stem cell proliferation. Acts upstream of or within several processes, including forebrain development; regulation of neural precursor cell proliferation; and regulation of neuron differentiation. Located in nucleus. Is expressed in several structures, including heart; nervous system; sensory organ; skeleton; and urinary system. Orthologous to human NR2E1 (nuclear receptor subfamily 2 group E member 1).
