Abstract

Background: Opn5 is considered to regulate nonvisual photoreception in the retina and brain of animals. Results: Mouse and primate UV-sensitive Opn5 along with retinoid isomerase are localized in the preoptic hypothalamus. Conclusion: Mammalian Opn5 can function as a high sensitivity photosensor in the deep brain with the assistance of 11-cisretinal supplying system. Significance: Mammals, including humans, may detect short wavelength light within the brain via Opn5.
