PDF Receptor Signaling in Drosophila Contributes to Both Circadian and Geotactic Behaviors
The neuropeptide Pigment-Dispersing Factor (PDF) is a principle transmitter regulating circadian locomotor rhythms in Drosophila. We have identified a Class II (secretin-related) G protein-coupledExpand
Isolation, identification and synthesis of locustamyoinhibiting peptide (LOM-MIP), a novel biologically active neuropeptide from Locusta migratoria
A novel peptide termed locustamyoinhibiting peptide (LOM-MIP) was isolated from brain-corpora cardiaca-corpora allata-suboesophageal ganglion extracts of the locust, Locusta migratoria. The primaryExpand
The Kinin Peptide Family in Invertebrates
Abstract: Kinins comprise a family of peptides that were first found in the central nervous system of insects and recently also in mollusks and crustaceans. After the isolation of the first membersExpand
Isolation and Identification of a Sulfakinin-Like Peptide, with Sequence Homology to Vertebrate Gastrin and Cholecystokinin, from the Brain of Locusta Migratoria
A neuropeptide (pGlu-Leu-Ala-Ser-Asp-Asp-Tyr-Gly-His-Met-Arg-Phe-NH2) with a blocked N-terminus and related to leucosulfakinins I and II from the Madeira roach has been isolated from an extract ofExpand
Isolation and characterization of eight myoinhibiting peptides from the desert locust, Schistocerca gregaria: new members of the cockroach allatostatin family
Eight myoinhibiting peptides were purified by high performance liquid chromatography from a methanolic extract of 7000 brains of the desert locust, Schistocerca gregaria. Complete sequences wereExpand
Isolation of NEB-LFamide, a novel myotropic neuropeptide from the grey fleshfly
A methanolic extract of 350,000 adult grey fleshflies Neobellieria bullata, was prepared and screened for myotropic activity. After fractionation on the first column, all fractions were screened inExpand
Locustatachykinin III and IV: two additional insect neuropeptides with homology to peptides of the vertebrate tachykinin family
Two myotropic peptides termed locustatachykinin III and IV were isolated from 9000 brain-corpora cardiaca-corpora allata-suboesophageal ganglion extracts of the locust, Locusta migratoria. TheExpand
Molecular cloning of the precursor cDNA for schistostatins, locust allatostatin-like peptides with myoinhibiting properties
The cDNA encoding the precursor polypeptide for schistostatins, allatostatin-like peptides which have been shown to inhibit peristaltic movements of the lateral oviducts of Schistocerca gregaria, hasExpand
Lom-AG-myotropin: A novel myotropic peptide from the male accessory glands of Locusta migratoria
A myotropic peptide, termed Lom-AG-myotropin, was isolated from extracts of 4400 accessory gland complexes of males of the locust, Locusta migratoria; the following sequence was derived:Expand
Ecdysteroids: the overlooked sex steroids of insects? Males: the black box
Abstract The paradigm, still around in textbooks, that ‘in insects sex is strictly genetic, thus that they do not have sex hormones’, is mainly based on a wrong interpretation of the ‘gynandromorphExpand
