Summary
Description
Participates in the primary piRNA biogenesis pathway and is required during spermatogenesis to repress transposable elements and prevent their mobilization, which is essential for the germline integrity (PubMed:23970546, PubMed:26919431). The piRNA metabolic process mediates the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins (Siwi or Ago3) and govern the methylation and subsequent repression of transposons (PubMed:23970546, PubMed:26919431). Required for the final steps of primary piRNA biogenesis by participating in the processing of 31-37 nt intermediates into mature piRNAs: acts by recruiting the exonuclease PNLDC1/trimmer to Siwi-bound pre-piRNAs (PubMed:26919431).
Participates in a complex which severs microtubules in an ATP-dependent manner. May act to target the enzymatic subunit of this complex to sites of action such as the centrosome. Microtubule severing may promote rapid reorganization of cellular microtubule arrays and the release of microtubules from the centrosome following nucleation.
Involved in the piwi-interacting RNA (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 which is essential for germline integrity (PubMed:21447556, PubMed:29531043). Likely to act by recruiting Piwi proteins such as AGO3 and piwi to the piRNA biogenesis machinery in the nuage (PubMed:21447556, PubMed:29531043). Required for the final steps of primary piRNA biogenesis by participating in the 3' end-trimming of piwi-bound intermediates into mature piRNAs (PubMed:29531043).
Subunit
Interacts with (symmetrically methylated) Siwi (PubMed:23970546, PubMed:26919431). Interacts with (symmetrically methylated) Ago3 (PubMed:23970546). Interacts with PNLDC1/trimmer; interaction takes place on the mitochondrial surface and recruits PNLDC1/trimmer to Siwi-bound pre-piRNAs (PubMed:26919431).
Interacts with KATNA1. This interaction enhances the microtubule binding and severing activity of KATNA1 and also targets this activity to the centrosome.
Interacts (via C-terminus) with AGO3 (via the N-terminal region when symmetrically methylated on arginine residues); this interaction is RNA-independent and may be required for AGO3 localization to the nuage (PubMed:21447556). Interacts (via Tudor domain) with piwi (via N-terminus) (PubMed:21447556, PubMed:29531043). Interacts with tral and me31B (PubMed:21447556).

Nucleus
Component of the meiotic nuage, also named P granule, a germ-cell-specific organelle required to repress transposon activity during meiosis. Expressed in the cytoplasm of germline stem cells, cyst cells, nurse cells and oocytes, with strong accumulation in region IIb germline cysts in the germarium. In post-germarium egg chambers accumulates in the perinuclear loci that appear to be the nuage. With evidence from 7 publications.
