Plays a central role during spermatogenesis by repressing transposable elements and preventing their mobilization, which is essential for the germline integrity (By similarity).
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 (By similarity).
Directly binds piRNAs, a class of 24 to 30 nucleotide RNAs that are generated by a Dicer-independent mechanism and are primarily derived from transposons and other repeated sequence elements (By similarity).
Associates with secondary piRNAs antisense and PIWIL2/MILI is required for such association (By similarity).
The piRNA process acts upstream of known mediators of DNA methylation (By similarity).
Does not show endonuclease activity (By similarity).
Plays a key role in the piRNA amplification loop, also named ping-pong amplification cycle, by acting as a 'slicer-incompetent' component that loads cleaved piRNAs from the 'slicer-competent' component PIWIL2 and target them on genomic transposon loci in the nucleus (By similarity).
May be involved in the chromatin-modifying pathway by inducing 'Lys-9' methylation of histone H3 at some loci.
