  • Title: A new gene nested within the dunce genetic unit of Drosophila melanogaster.
    Author: Furia M, Digilio FA, Artiaco D, Giordano E, Polito LC.
    Journal: Nucleic Acids Res; 1990 Oct 11; 18(19):5837-41. PubMed ID: 2120680.
    Abstract:
    The molecular organization of the dunce gene of Drosophila melanogaster has proved to be particularly complex, with two divergently transcribed genes, Sgs-4 and Pig-1, nested within its 79 kb intron (1). Here we report the identification and the molecular characterization of a third gene nested within the transcription unit of dunce. This newly identified gene is located nearly 6 kb downstream Pig-1, within a more upstream dunce intron. The gene is developmentally regulated and transcribed with the same polarity of dunce; several lines of evidence indicate that it might encode for a salivary gland secreted (Sgs) protein.
