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 peptide YY (PYY) and 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.2
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.3 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
NPY2R is primarily expressed in neurons as a presynaptic receptor. It is also strongly expressed in epithelia of the visceral tissues, including colon and kidney.4 NPY2R is involved in inhibition of neurotransmitter release mediated by NPY.5 Release of glutamate, the principal neuroexcitatory transmitter, is inhibited via the NPY2R receptor.6 Involvement of NPY2R in feeding behavior was also reported. PYY(3?6), an NPY2R agonist, acts to inhibit feeding via NPY2R.7
Alomone Labs is pleased to offer a highly specific antibody directed against an intracellular epitope of the mouse neuopeptide Y2 receptor (NPY2R). Anti-NPY2R antibody (#ANR-022) can be used for Western blot analysis and immunocytochemical staining applications and should recognize NPY2R from human, rat, and mouse samples.
