Isolation and sequencing of two FMRFamide-related peptides from the gut of Locusta migratoria L.
Peptides. 2007 Aug; 28(8):1490-7.P

Abstract

Two FMRFamide-related peptides (FaRPs) have been isolated and sequenced from the whole gut of Locusta migratoria L. Peptides were extracted from 500 locust whole guts and separated using reversed-phase high performance liquid chromatography (RP-HPLC). Fractions containing FMRFamide-like immunoreactive (FLI) material were identified using radioimmunoassay (RIA). Sequencing of fractions, using tandem mass spectrometry (MALDI-TOF MS/MS), revealed the myosuppressin previously isolated from the locust CNS, SchistoFLRFamide (PDVDHVFLRFamide), and a novel extended RFamide (LWENLRFamide). The isolation of SchistoFLRFamide from midgut tissue supports the hypothesis that this myosuppressin is released locally from FLI processes over the gut and/or from endocrine-like midgut cells to play a role in the regulation of digestion.
