Abstract
Family-B G protein-coupled receptors (GPCR-Bs) play vital roles in many biological processes, including growth, development and reproduction. However, the evolution and function of GPCR-Bs have been poorly understood in insects. We have identified 87 GPCR-Bs from six model insect species, 20 from Tribolium castaneum, 9 from Apis mellifera, 11 from Bombyx mori, 9 from Acyrthosiphon pisum, 14 from Anopheles gambiae and 24 from Drosophila melanogaster. 22 of them were reported in this study for the first time. Phylogenetic analysis revealed that there are three kinds of evolutionary patterns that occurred among GPCR-Bs during insect evolution: one-to-one orthologous relationships, species-specific expansion and episodic duplication or loss in certain insect lineages. A striking finding was the discovery of a parathyroid hormone receptor like gene (pthrl) in invertebrates, which was independently duplicated in vertebrates and invertebrates, whereas this gene was lost at least twice during insect evolution. These results indicate that PTHRL is possibly divergent in the functions between mammals and insects. The information of family-B GPCRs in nondrosophiline insects has been established, and will promote the further study on the function of these GPCRs and deorphanization of them. On the other hand, this study provides us with multiple function of GPCR-Bs in differential organisms, which will be also the potential attacking targets for new pesticides and drugs.

Abstract
Neuropeptides and protein hormones constitute a very important group of signaling molecules, regulating central physiological processes such as reproduction, development, and behavior. Using a bioinformatics approach, we screened the recently sequenced genome of the parasitic wasp, Nasonia vitripennis, for the presence of these signaling molecules and annotated 30 precursor genes encoding 51 different mature neuropeptides or protein hormones. Twenty-four of the predicted mature Nasonia neuropeptides could be experimentally confirmed by mass spectrometry. We also discovered a completely novel neuropeptide gene in Nasonia, coding for peptides containing the C-terminal sequence RYamide. This gene has orthologs in nearly all arthropods with a sequenced genome, and its expression in mosquitoes was confirmed by mass spectrometry. No precursor could be identified for N-terminally extended FMRFamides, even though their putative G protein coupled receptor (GPCR) is present in the Nasonia genome. Neither the precursor nor the putative receptor could be identified for allatostatin-B, capa, the glycoprotein hormones GPA2/GPB5, kinin, proctolin, sex peptide, and sulfakinin, arguing that these signaling systems are truly absent in the wasp. Also, antidiuretic factors, allatotropin, and NPLP-like precursors are missing in Nasonia, but here the receptors have not been identified in any insect, so far. Nasonia (Hymenoptera) has the lowest number of neuropeptide precursor genes compared to Drosophila melanogaster, Aedes aegypti (both Diptera), Bombyx mori (Lepidoptera), Tribolium castaneum (Coleoptera), Apis mellifera (Hymenoptera), and Acyrthosiphon pisum (Hemiptera). This lower number of neuropeptide genes might be related to Nasonia's parasitic life.

Abstract
A pigment-dispersing hormone (PDH) from eyestalks of the fiddler crab Uca pugilator has been purified by gel filtration, ion-exchange chromatography, partition chromatography, and reversed-phase liquid chromatography. Based on automated gas-phase sequencing and subsequent identification of carboxyl-terminal amide, we have assigned the primary structure of this peptide as Asn-Ser-Glu-Leu-Ile-Asn-Ser-Ile-Leu-Gly-Leu-Pro-Lys-Val-Met-Asn-Asp-Ala-NH (2). We have confirmed the sequence by synthesizing this peptide and demonstrating that the synthetic PDH and the native PDH display identical chromatographic behavior and biological activity. This hormone is a member of a family of invertebrate neuropeptides that includes a light-adapting/pigment-dispersing octadecapeptide hormone from the prawn Pandalus borealis. In assays for melanophore pigment dispersion in destalked fiddler crabs, Uca PDH was 21-fold more potent than Pandalus PDH. These two hormones share a hexapeptide core sequence (residues 5-10: -Ile-Asn-Ser-Ile-Leu-Gly-) as well as the amino- and carboxyl-terminal residues but differ at positions 3, 4, 11, 13, 16, and 17. These results point to speciesrelated or group-specific structural differences among crustacean PDHs.

Abstract
G protein-coupled receptor (GPCR) genes are large gene families in every animal, sometimes making up to 1-2% of the animal's genome. Of all insect GPCRs, the neurohormone (neuropeptide, protein hormone, biogenic amine) GPCRs are especially important, because they, together with their ligands, occupy a high hierarchic position in the physiology of insects and steer crucial processes such as development, reproduction, and behavior. In this paper, we give a review of our current knowledge on Drosophila melanogaster GPCRs and use this information to annotate the neurohormone GPCR genes present in the recently sequenced genome from the honey bee Apis mellifera. We found 35 neuropeptide receptor genes in the honey bee (44 in Drosophila) and two genes, coding for leucine-rich repeats-containing protein hormone GPCRs (4 in Drosophila). In addition, the honey bee has 19 biogenic amine receptor genes (21 in Drosophila). The larger numbers of neurohormone receptors in Drosophila are probably due to gene duplications that occurred during recent evolution of the fly. Our analyses also yielded the likely ligands for 40 of the 56 honey bee neurohormone GPCRs identified in this study. In addition, we made some interesting observations on neurohormone GPCR evolution and the evolution and co-evolution of their ligands. For neuropeptide and protein hormone GPCRs, there appears to be a general co-evolution between receptors and their ligands. This is in contrast to biogenic amine GPCRs, where evolutionarily unrelated GPCRs often bind to the same biogenic amine, suggesting frequent ligand exchanges ("ligand hops") during GPCR evolution.

Abstract
An in vitro crustacean (freshwater shrimp, Macrobrachium potiuna) erythrophore bioassay for chromatophorotropins and other pigment cell agonists is described. The present assay is a quantitative method that determines the pigment responses with the aid of an ocular micrometer. The pigment granules within the erythrophores are dispersed out into the dendritic processes of the cells when the isolated carapace is placed in physiological solution. This bioassay provides, therefore, a method for measuring the response of the pigment cells to aggregating agents such as pigment concentrating hormone (PCH). This bioassay is sensitive to PCH at a concentration as low as 3 x 10(-12) M. Calcium ionophore A23187 mimics the actions of PCH, but, unlike the hormone, the ionophore-induced pigment aggregation is irreversible after physiological solution rinses. Therefore, chromatophorotropic activities of pigment dispersing agents, such as pigment dispersing hormones (PDH), can be determined on ionophore-treated erythrophores. The potencies of alpha-PDH and beta-PDH show a threefold difference (not significant). Because of its convenience and its ability to make an objective determination of the bidirectional pigment movements within erythrophores, this bioassay is a suitable method for further structure-activity studies of the various chromatophorotropins and their analogs.

Abstract
This report summarizes recent work on the chemistry and structure-activity relationships of crustacean chromatophorotropic pigment-dispersing hormones (PDHs) and the identification of structurally related peptides from insects. So far, the primary structures of crustacean alpha-PDH and beta-PDH and of a pigment-dispersing factor (PDF) from the grasshopper Romalea microptera have been deduced. Additionally, 17 of the 18 residues of a PDF from the cricket Acheta domesticus were identified. In the PDH/PDF family, the chain length (18 residues), terminal residues (N-terminal Asn and C-terminal Ala-NH2), and at least 50% of the amino acid sequence appear to be conserved. The functions of these peptides in insects are unknown. Detailed studies of structure-activity relationships of crustacean PDHs have been conducted, leading to the tentative identification of the message sequence, preparation of hyperpotent oxidation-resistant analogs, and synthesis of bioactive tyrosinated analogs for radioiodination. Antisera were raised against PDHs, and immunoreactive soma and fibers have been localized in the crustacean eyestalk neurosecretory system. This progress is expected to stimulate more intensive research on the PDH family.

Abstract
In an effort to explain the difference in potencies between the two characterized crustacean pigment-dispersing hormones (alpha-PDH; beta-PDH) and to define a role for residue 3 in these octadecapeptide hormones, we have synthesized and purified seven position 3 alpha-PDH analogues ([Ala3], [Ile3], [Asn3], [Gln3], [Asp3], [Glu3], and [Lys3]alpha-PDH). When tested for melanophore pigment-dispersing activity in destalked Uca, [Glu3]alpha-PDH was found to be 325% more potent than alpha-PDH. Reduced potencies were observed for the [Asp3] (58%), [Asn3] (26%), [Gln3] (11%), and [Ala3] (8%) derivatives. Much lower potencies were displayed by the [Lys3] and [Ile3] analogues (0.73% and 0.66%, respectively). These results suggest that the position 3 side chain carboxylate anion of [Glu3]alpha-PDH stabilizes the active receptor-bound conformer through a charge-charge interaction.

Abstract
This study deals with the effect of deamidation and C-terminal truncation on the potency of an octadecapeptide pigment-dispersing hormone (PDH: Asn-Ser-Gly-Met-Ile-Asn-Ser-Ile-Leu-Gly-Ile-Pro-Arg-Val-Met-Thr-Glu-Ala- NH2), first described as light-adapting distal retinal pigment hormone (DRPH) from Pandalus borealis. Bioassay of synthetic analogs for melanophore pigment dispersion in destalked fiddler crabs (Uca pugilator) showed that deamidation causes a 300-fold decrease in potency. The analogs 1-17 NH2 and 1-16 NH2 were about 3 times more potent than 1-18-OH. Further truncation led to decreases in potency, with the peptide 1-9-NH2 being the smallest C-terminal deletion analog to display activity (0.001% potency). Smaller analogs (1-8-NH2, 1-6-NH2 and 1-4-NH2) were inactive when tested in doses as high as 500 nmoles/crab. On the basis of our earlier work on N-terminal deletion analogs and the present findings the residues 6 to 9 seem to be important for PDH action.

Abstract
In order to evaluate the structural/functional roles of Met residues in an octadecapeptide pigment-dispersing hormone (PDH: Asn-Ser-Gly-Met-Ile-Asn-Ser-Ile-Leu-Gly-Ile-Pro-Arg-Val-Met-Thr-Glu-Ala- NH2), first described as light-adapting distal retinal pigment hormone (DRPH) from Pandalus, three analogs were synthesized: Nle4-PDH, Nle15-PDH, and Nle4,15-PDH. When tested for melanophore pigment-dispersing activity in destalked Uca, all three Nle-analogs were more potent than unsubstituted PDH. Performic acid oxidation caused a marked loss of potency of PDH, Nle4-PDH, and Nle15-PDH. The analog Nle4,15-PDH was resistant to oxidation and displayed 6-fold higher potency than PDH. Thus Met4 and Met15 are not essential for the PDH activity. The oxidation-induced loss of activity of unsubstituted PDH may result from introduction of oxygen (in methionine sulfone) and a consequent conformational change in the octadecapeptide.

Abstract
The development of a long-term research program on the neurosecretory hormones of arthropods is described. The purification and full characterization of the first invertebrate neurohormones, the red pigment-concentrating hormone (RPCH) and the distal retinal pigment hormone (DRPH) demonstrated that they are peptides, an octapeptide and an octadecapeptide, respectively. Physiological function studies with the pure hormones and their synthetic preparations showed that the RPCH acts as a general pigment-concentrating hormone (PCH), and that the DRPH, in addition to its light-adaptive function, also constitutes a general pigment-dispersing hormone (PDH). In the regulation of the color-adaptation of the animals, the two hormones act as antagonists. The chromatophorotropic activities are widely distributed within the arthropod neuroendocrine systems. Purification of the pigment-concentrating activities from the locust corpora cardiaca lead to the isolation and characterization of the first insect neurohormones, the adipokinetic hormones (AKH I and AKH II). These two hormones, AKH I being a decapeptide and AKH II being an octapeptide, are close structural analogs to the crustacean PCH, demonstrating a common evolution of arthropod neurohormones. The hormones of this PCH-family all cross-react, but structure-function studies of the hormones show that quite different parts of their structure are involved in their binding to the various receptors.
