Japan The photopigment melanopsin has been suggested to act as a dominant photoreceptor in nonvisual photoreception including resetting of the circadian clock (entrainment), direct tuning or masking of vital status (activity, sleep/wake cycles, etc.), and the pupillary light reflex

These 'nonvisual' light responses have been suggested to be predominantly mediated by the novel photopigment melanopsin Pituitary adenylate cyclase-activating polypeptide (PACAP) belongs to the vasoactive intestinal polypeptide (VIP)/glucagons/secretin family and plays pleiotropic roles as a neurotransmitter, neuromodulator and neurotrophic factor

Adcyap1 −/− mice could be also related to melanopsin-mediated phototransduction, because melanopsin is a photoreceptor that is exclusively colocalized in PACAP-expressing ganglion cells in the retina
