Figure 1. Nucleotide and amino acid sequences of the MdHexLI and MdHexFI hexamerin genes of Musca domestica. A) Schematic representation of the genomic clone containing the MdHexL1 gene. The coding region is indicated by a black box (Top). Complete nucleotide sequence of the MdHexL1 gene coding region and putative promoter (Bottom). A TATA motif is indicated by bold characters in grey background, the transcription start site is underlined, the putative ecdysone responsive element is double underlined, polyadenylation signals are boxed, and the conserved hexamerin amino acid motifs are underlined with dashed lines. The intron sequence is shown in lower-case letters. B) Schematic representation of the genomic clone containing the MdHexF genes (Top). Complete nucleotide sequence of the MdHexF1 gene coding region and putative promoter (Bottom). Promoter elements, polyadenylation signals and conserved amino acid sequences are indicated as for (A). The partial mariner element is indicated in gray background, between positions -940 and -739. GenBank accession numbers: MdHexL1=AY256680, MdHexF1=AY256681, MdHexF2=AY258291..
