Scientific background: |
NPY1R, Neuropeptide Y receptor Y1, is a protein that in humans is encoded by the NPY1R gene. NPY receptor is a member of the G protein-coupled receptor superfamily. The NPY Y1 receptor gene has 3 exons. By high resolution fluorescence in situ hybridization, the NPY1R gene is localized to chromosome 4q31.3-q32. NPY is one of the most abundant neuropeptides in the mammalian nervous system and exhibits a diverse range of important physiologic activities, including effects on psychomotor activity, food intake, regulation of central endocrine secretion, and potent vasoactive effects on the cardiovascular system. Two major subtypes of NPY (Y1 and Y2) have been defined by pharmacologic criteria. NPY receptors have been identified in a variety of tissues, including brain, spleen, small intestine, kidney, testis, placenta, and aortic smooth muscle. |
