CIb1 promoter
RNA ElementThe CIb1 promoter is a Bombyx mori gene promoter characterized by firefly luciferase reporter assays in the ovary-derived BmN cell line. Deletion analysis identified promoter fragments with transcriptional activity, including an 82 bp region from -72 to +10 nt that retains basic promoter function, and an upstream segment with strong negative regulatory effects.
