  • Function

    Probable ATP-binding RNA helicase which plays a central role during spermatogenesis and oogenesis by repressing transposable elements and preventing their mobilization, which is essential for the germline integrity. Acts via the piRNA metabolic process, which mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi and govern the methylation and subsequent repression of transposons. Involved in the repression of LTR retrotransposon copia. Also involved in telomere regulation by repressing specialized telomeric retroelements HeT-A, TAHRE, and TART; Drosophila telomeres being maintained by transposition of specialized telomeric retroelements. Involved in telomeric trans-silencing, a repression mechanism by which a transposon or a transgene inserted in subtelomeric heterochromatin has the capacity to repress in trans in the female germline, a homologous transposon, or transgene located in euchromatin. Involved in the repression of testis-expressed Stellate genes by the homologous Su(Ste) repeats. Required for anteroposterior and dorsoventral axis formation during oogenesis.
  • Sequence similarities

    Belongs to the DEAD box helicase family. DEAH subfamily.
    Contains 1 helicase ATP-binding domain.
    Contains 1 helicase C-terminal domain.

  • Cellular localization

    Cytoplasm. Component of the nuage, also named P granule, a germ-cell-specific organelle required to repress transposon during meiosis.

    Customer reviews and Q&As


    Thank you for your enquiry. Spindle-E is part of the RNA interference machinery and therefore a nuclear protein. You may wish to consult the reference: Heterochromatic silencing and HP1 localization in Drosophila are dependent on the RNAi machinery. 2004. Pal-Bhadra M, Leibovitch BA, Gandhi SG, Rao M, Bhadra U, Birchler JA, Elgin SC. Science. 30;303(5658):669-72.
