Enables protein heterodimerization activity and protein homodimerization activity. Involved in several processes, including circadian temperature homeostasis; mating; and regulation of gene expression. Located in cell body; cytoplasm; and nucleus. Is expressed in several structures, including central nervous system; digestive system; integumentary system; pacemaker neurons; and reproductive system. Human ortholog(s) of this gene implicated in advanced sleep phase syndrome; advanced sleep phase syndrome 1; and advanced sleep phase syndrome 3. Orthologous to several human genes including PER3 (period circadian regulator 3). [provided by Alliance of Genome Resources, Apr 2022]
