    Scientific background

    Neuropeptide Y (NPY) is a 36-amino acid peptide neurotransmitter in the central (CNS) and peripheral nervous systems.1 It belongs to the NPY family, together with the peptide YY (PYY) and the pancreatic polypeptide (PP). NPY is involved in regulation of a broad range of homeostatic functions such as eating behavior, hypertension, and reproduction.2

    NPY exerts its effects via five receptor subtypes known as the neuropeptide Y receptors (NPYR): Y1 (NPY1R), Y2 (NPY2R), Y4 (NPY4R), Y5 (NPY5R) and Y6 (NPY6R).2 Four of these, Y1, Y2, Y4, and Y5, are expressed in humans.

    The NPY receptors belong to the G protein-coupled receptor superfamily whose members share a common structure of seven putative transmembrane domains, an extracellular amino terminus, and a cytoplasmic carboxyl terminus.

    Activation of these receptors by NPY produces effects on [Ca2+]i, adenylate cyclase, and a number of ion channels.Based on the high frequency and density of NPY receptors in steroid hormone-producing tumors, the NPY receptors might be of potential use in tumor management.2

    NPY1R is considered to be a postsynaptic receptor. In the CNS, NPY1Rs are concentrated in the cortical areas of the brain, cerebral cortex, olfactory nucleus, hippocampus, hypothalamic nuclei, and thalamic nuclei.4 In addition, this receptor has a bimodal role in the immune system, serving as a strong negative regulator on T cells as well as a key activator of antigen-presenting cell function.5

    Last update: 17/02/2020

    Alomone Labs is pleased to offer a highly specific antibody directed against an intracellular epitope of the human neuopeptide Y1 receptor (NPY1R). Anti-NPY1R Antibody (#ANR-021) can be used in western blot analysis, immunohistochemistry, and immunocytochemical applications. It has been designed to recognize NPY1R from human, rat, and mouse samples.
