- ... We studied the promoter activity of a 5'-flanking region from -5000 to +24 (-5000/+24) in Bombyx mori fibroin heavy chain gene (fibH), fibH(-5000/+24). A luciferase reporter vector carrying fibH(-5000/+24) was bombarded to isolated posterior silk glands (PSGs). The PSGs showed a high luciferase activity when transplanted to larvae, indicating its potent promoter activity. Deletion experiments show ...
