A recent analysis of the genome ofLocusta migratoriaindicated the presence of four novel insect neuropeptide genes encoding for multiple tryptopyrokinin peptides (tryptoPKs); hitherto only known frompyrokininorcapagenes. In our study, mature products oftryptoPKgenes 1 and 2 were identified by mass spectrometry; precursor sequences assigned to thetryptoPKgenes 3 and 4 are likely partial sequences of a single precursor. The expression oftryptoPKgenes 1 and 2 is restricted to two cells in the subesophageal ganglion, exhibiting not only a unique neuropeptidome but also a very distinctive axonal projection. Comparative neuroendocrinology revealed that homologous cells in other insects also produce tryptoPKs but use other genes to generate this pattern. Sincecapaandpyrokiningenes are discussed as ancestors of thetryptoPKgenes, we completed the hitherto only partially known precursor sequences of these genes by means of transcriptome analyses. The distribution of mature products of CAPA and pyrokinin precursors in the CNS is compared with that of tryptoPKs. In addition, a novel pyrokinin-like precursor is described.
