Structure and expression of the Kap (CG11759) transcription unit (region 10B of X chromosome; FlyBase, 2002; Sarpal & Ray, 2002). (A) Genomic organization. The Kap transcript contains nine exons (black bars: coding region; white boxes: untranslated sequences). Position of the L(1)G0396 P-element insertion is marked. The sequence of Kap is shown in supplementary Fig 1 online. (B–E) Expression patterns in a Drosophila follicle (B) and embryos (C–E) as revealed by whole-mount in situ hybridization of a Kap-specific RNA probe; orientation: anterior left and dorsal up. Note strong Kap expression in nurse cells (stage 9) (B), a ubiquitous distribution of maternal transcripts in a stage 2 embryo (C), zygotic expression in ectodermal and mesodermal derivatives (stage 12 embryo) (D) and the enrichment of transcripts in the central and peripheral nervous systems in older embryos (E; details in Sarpal & Ray, 2002).
