The c(3)G (CG17604) locus. (A) The genomic structure of c(3)G (CG17604), based on the GM04379 and LD07655 cDNAs (Rubin et al. 2000); surrounding genes are shown as boxes representing exons. Genomic DNA coordinates in base pairs are from the Gadfly Drosophila genome annotation database (FlyBase 1999). The c(3)G (CG17604) open reading frame is shown in gray. c(3)G mutations are represented below the intron/exon structure of CG17604. CG18505 is encoded on the opposite strand as c(3)G, largely within the c(3)G 5′ untranslated region. (B) Rescue constructs P{X203} and P{X204} include genomic DNA from between the XbaI and XhoI sites indicated in A. P{X204} bears a deletion between the HindIII sites (shown in A) within the CG17604 gene.
