title: [Molecular and physiological characterization of the pyrokinin insect neuropeptide family].
abstract: Peptides from the pyrokinin (PK) family are a large, structurally and functionally diverse group of the insect neuropeptides produced by neurosecretory cells of the insect nervous system. This family contains short and long peptides which share C-terminal -FXPRLa amino acid sequence. Pyrokinins regulate the visceral muscle contractions, pheromone biosynthesis, pupariation and diapause duration in insects. They are encoded by two genes PBAN and capa, which are mainly expressed in the suboesophageal ganglion. Peptides are then transported to the retrocerebral complex and released into haemolymph. Recent studies are focused on application of pyrokinins as biopesticides in the regulation of insect pests growth and development.
