Predicted to enable RNA polymerase II cis-regulatory region sequence-specific DNA binding activity and nuclear receptor activity. Predicted to be involved in several processes, including hormone-mediated signaling pathway; intracellular receptor signaling pathway; and regulation of transcription by RNA polymerase II. Predicted to act upstream of or within regulation of DNA-templated transcription. Predicted to be active in nucleus. Is expressed in nervous system; optic vesicle; and pharyngeal arch. Orthologous to human NR1D2 (nuclear receptor subfamily 1 group D member 2).
