Enables DNA binding activity. Involved in several processes, including positive regulation of behavioral fear response; regulation of gene expression; and response to redox state. Acts upstream of or within circadian sleep/wake cycle and locomotor rhythm. Predicted to be located in cytosol and nucleoplasm. Predicted to be part of CLOCK-BMAL transcription complex. Is expressed in several structures, including central nervous system; early conceptus; genitourinary system; intestine; and retina. Orthologous to human NPAS2 (neuronal PAS domain protein 2).
