摘要
Pheromone biosynthesis activating neuropeptide (PBAN) is a suboesophageal ganglion secretory polypeptide of insect, which activates the pheromone gland to produce sex pheromone biosynthesis in female silkworm, Bombyx mori. A Bombyx genomic library was screened by the method of plaque hybridization using the 32P-labeled BomDH cDNA as a probe. The genomic sequence encoding PBAN has been cloned and its structure is analyzed. The PBAN gene comprises two exons interspersed by a single intron 697 bp in length. Preceding the PBAN amino acid sequence is a 32-amino acid sequence containing two FXPRL amide peptides, which are α-SGNP (Ile-Ile-Phe-Thr-Pro-Lys-Leu) and β-SGNP (Ser-Val-Ala-Asn-Pro-Arg-Thr-His-Glu-Ser-Leu-Glu-Phe-Ile-Pro-Arg-Leu), which is followed by a Gly-Arg processing site. Immediately, after the PBAN amino acid sequence is a Gly-Arg processing site and a FXPRL amide peptide γ-SGNP (Thr-Met-Ser-Phe-Ser-Pro-Arg-Leu). It is suggested that besides PBAN, 7-, 8-, and 17-residue amidated peptides wer
