VIP and PACAP receptor 2, or VIPR2 encodes the VPAC2 receptor, which binds both VIP and PACAP. VPAC2 is expressed throughout the central nervous system and the periphery. Mutations in the VIPR2 homolog in the mouse cause hypoactivity, as well as disruptions in circadian rhythm. Duplications of the neuropeptide receptor gene VIPR2 confer significant risk for schizophrenia.
