  • Function

    Plays a central role during spermatogenesis by participating in the repression 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 proteins and governs the methylation and subsequent repression of transposons. Required for the localization of Piwi proteins to the meiotic nuage. Involved in the piRNA metabolic process by ensuring the entry of correct transcripts into the normal piRNA pool and limiting the entry of cellular transcripts into the piRNA pathway. May act by allowing the recruitment of piRNA biogenesis or loading factors that ensure the correct entry of transcripts and piRNAs into Piwi proteins.
  • Tissue specificity

    Testis and ovary specific. Also expressed in several cancers.
  • Sequence similarities

    Belongs to the TDRD1 family.
    Contains 1 MYND-type zinc finger.
    Contains 4 Tudor domains.
  • Domain

    Tudor domains 2 and 3 have higher affinity for arginine-methylated peptides, tudor domain 1 is a poor binder due to an impaired aromatic cage.
  • Cellular localization

    Cytoplasm. Component of the meiotic nuage, also named P granule, a germ-cell-specific organelle required to repress transposon activity during meiosis. Also present in chromatoid body (By similarity).
