Description

Full-length human NPY2R cDNA encoding Y2, The NPY family consists of three 36-amino acid peptides, neuropeptide Y (NPY), peptide YY (PYY) and pancreatic polypeptide (PP), which bind to the NPY receptor family of G protein-coupled receptors. Five NPY receptors, Y1, Y2, Y4, Y5 and Y6, have been defined at the molecular level, and each signals primarily through Gi/o. Binding of NPY family peptides to NPY receptors mediates a variety of physiological effects, including promotion of food intake, decreased anxiety, inhibition of neurotransmitter and hormone release, vasoconstriction, and gut motility. Y2 is primarily expressed in the CNS, and it mediates presynaptic inhibition of neurotransmitter release (Michel et al., 1998). Chemicon's Y2 membrane preparations are crude membrane preparations made from our proprietary stable recombinant cell lines to ensure high-level of GPCR surface expression, thus, they are ideal HTS tools for screening of antagonists of Y2 interactions and its ligands. The membrane preparations exhibit a Kd of 1.28 nM for [125I]-human PYY. With 0.5 nM [125I]-human PYY, 5 or 10µ,g/well Y2 Membrane Prep yields greater than 10-fold signal-to-background ratio.
