Fig. 1. (A) The complete amino acid sequence of Ag-ASH is compared with that of the achaete-scute homologue of the butterfly Precis coenia (Galant et al., 1998) and with lethal of scute from Drosophila (D.m. Lscute) (Villares and Cabrera, 1987). Differences are shown in black. The start site is indicated by a green circle. Conservation is highest in the bHLH domain, which is boxed. The shaded blue box indicates a conserved stretch in the C-terminal domain. (B) The complete amino acid sequence of Ag-Pnr is compared with that of the Pannier protein of Drosophila melanogaster and Ceratitis capitata. Differences are shown in black. The start site is indicated by a green circle. The two zinc fingers are boxed. The
helical structures are shown as shaded blue boxes. The nuclear localisation signal (NLS) is indicated by the shaded grey box.
