Figure 1: Drosophila ADAR localizes to the Caps locus in salivary gland polytene nuclei.

(a–c) Third instar larval polytene nuclei in a, magnified in b and chromosomal squashes in c expressing dADAR-HA driven by elav-Gal4 and immunostained for the nucleolar marker Fibrillarin (FIB). (d) Transgenic dADAR driven by elav-Gal4 localizes to the Caps locus, labelled using a FISH DNA probe. Chromosome 4 is denoted in d. Arrows point to prominent localization of dADAR-HA on the tip of chromosome 4. Scale bars, 20 μm.
