Function | Plays a central role during spermatogenesis 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 proteins and governs the methylation and subsequent repression of transposons. 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. Associates with secondary piRNAs antisense and PIWIL2/MILI is required for such association. The piRNA process acts upstream of known mediators of DNA methylation. Participates in a piRNA amplification loop. Besides their function in transposable elements repression, piRNAs are probably involved in other processes during meiosis such as translation regulation. {ECO:0000269PubMed:17395546, ECO:0000269PubMed:18381894, ECO:0000269PubMed:18922463}. | ||||||||||||||||
Subcellular Localization | Nucleus. Cytoplasm. Note=Probable component of the meiotic nuage, also named P granule, a germ-cell-specific organelle required to repress transposon activity during meiosis. PIWIL2/MILI is required for nuclear localization. | ||||||||||||||||

Tissue Specificity | Detected in male germ cells beginning around 14.5-15.5 dpc but is absent from female germ cells. From 15.5 dpc and until birth, it is present in male germ cells. Not detected in somatic cells of the embryonic gonad. Expression declines soon after birth, reaching undetectable levels in 4 day-old mice (at protein level). {ECO:0000269PubMed:18922463}. | ||||||||||||||||
