Neuropeptide Y Receptor Subtypes, Y1 and Y2

Annals of the New York Academy of Sciences, 1990
Heterogeneity among NPY (and PYY) receptors was first proposed on the basis of studies on sympathetic neuroeffector junctions, where NPY (and PYY) can exert three types of action: 1) a direct (e.g., vasoconstrictor) response; 2) a postjunctional potentiating effect on NE-evoked vasoconstriction; and 3) a prejunctional suppression of stimulated NE ...

Neuropeptide Y receptor subtypes

Life Sciences, 1995
Neuropeptide Y (NPY) is an amidated 36-amino acid peptide with a wide distribution in the central and peripheral nervous system. It can evoke numerous physiological responses by activating specific receptors. Studies using NPY analogs in various model systems and cell types demonstrate different orders of ligand potency and receptor binding affinity ...

The G-protein-coupled neuropeptide Y receptor type 2 is highly dynamic in lipid membranes as revealed by solid-state NMR spectroscopy.

Chemistry, 2014
In spite of the recent success in crystallizing several G-protein-coupled receptors (GPCRs), a comprehensive biophysical characterization of these molecules under physiological conditions also requires the study of the molecular dynamics of these ...

Subtypes Y1 and Y2 of the neuropeptide Y receptor are respectively expressed in pro-opiomelanocortin- and neuropeptide-Y-containing neurons of the rat hypothalamic arcuate nucleus.

Neuroendocrinology, 1997
The arcuate nucleus of the hypothalamus houses a number of neurochemically different cell populations. Among these, a dense cluster of small neuropeptide-Y (NPY)-expressing neurons is located in its ventromedial subdivision and a pro-opiomelanocortin ...

Neuropeptide Y receptor antagonists in obesity

Expert Opinion on Investigational Drugs, 1997
Neuropeptide Y (NPY) is a 36 amino acid amidated peptide with high sequence homology to the endocrine peptides, peptide YY (PYY) and pancreatic polypeptide (PP). They appear to interact with a family of receptors that possess high affinity for one or more of these peptides.

Neuropeptide Y Receptor in Vascular Smooth Muscle

Journal of Neurochemistry, 1991
Abstract: 125I‐Bolton‐Hunter (125I‐BH) neuropeptide Y (NPY) was used to identify specific high‐affinity NPY binding sites in porcine aortic smooth muscle membrane fractions and to characterize the binding sites in comparison with those in porcine hippocampal membrane fractions.
