Evolution of the neuropeptide Y receptor family: gene and chromosome duplications deduced from the cloning and mapping of the five receptor subtype genes in pig.
The sequence comparisons suggest that the tight cluster of NPY1R, NPY2R, and NPY5R on human chromosome 4 (HSA4) represents the ancestral configuration, whereas the porcine cluster has been split by two inversions on SSC8.
Multiplicity of neuropeptide Y receptors: cloning of a third distinct subtype in the zebrafish.
This work suggests that NPY has more receptor subtypes than any other peptide that binds to G protein-coupled receptors, and work is in progress to see if the zebrafish receptors are present in mammals.
Receptor subtypes Y1 and Y5 mediate neuropeptide Y induced feeding in the guinea‐pig
It is shown that NPY stimulates feeding in guinea‐pigs through Y1 and Y5 receptors, which suggests that either Y1 or Y4 receptors or both may mediate NPY induced hyperphagia also in other orders of mammals.
Neuropeptide Y‐family receptors Y6 and Y7 in chicken
The phylogenetic and chromosomal analyses support the ancient origin of these Y receptor genes by chromosome duplications in an early (pregnathostome) vertebrate ancestor.
Development of binding and functional assays for the neuropeptide Y Y 2 and Y 4 receptors
The main advantage of the established aequorin assay is the automation of the injection and recording process, and it is possible to perform more than 400 single calcium assays per day compared to about 40 assays performed with the spectrofluorimetric or flow cytometric calcium assay.


Sequence and expression of a neuropeptide Y receptor cDNA.
The polymerase chain reaction was used to isolate novel GTP-binding protein (G protein)-coupled receptors from bovine locus coeruleus (LC), a brain region enriched in the neuropeptide Y (NPY) system,
Cloning and functional characterization of a family of human and mouse somatostatin receptors expressed in brain, gastrointestinal tract, and kidney.
The cloning, functional expression, and tissue distribution of two different somatostatin receptors (SSTRs) are reported, showing that SSTR1 and SSTR2 are expressed at highest levels in jejunum and stomach and in cerebrum and kidney, respectively.
The human N-formylpeptide receptor. Characterization of two cDNA isolates and evidence for a new subfamily of G-protein-coupled receptors.
Two variants of the human N-formylpeptide chemoattractant receptor have been isolated from a CDM8 expression library prepared from mRNA of human myeloid HL-60 cells differentiated to the granulocyte phenotype with Bt2cAMP, and sequence comparison established that the fMLP receptor belongs to the G-protein-coupled receptor superfamily.
Neuropeptide Y Receptor Subtypes, Y1 and Y2
Heterogeneity among NPY (and PYY) receptors was first proposed on the basis of studies on sympathetic neuroeffector junctions, and work has indicated that the Y2-receptor may occur postjunctionally in selected sympathetic effector systems.
Neuropeptide Y-related peptides and their receptors--are the receptors potential therapeutic drug targets?
It has been appreciated that NPY may also be an important messenger in its own right , perhaps particularly in the brain, where NP Y has been frequently used to study cotransmission, particularly in its relation to the "classical" neurotransmitter norepinephrine.
125I-neuropeptide Y and 125I-peptide YY bind to multiple receptor sites in rat brain.
It is proposed that rat brain contains a minor population of high affinity NPY binding sites with an intermediate dissociation rate and no sensitivity to Gpp(NH)p, a nonhydrolyzable analog of GTP.
