| Function |
Plays a central role during spermatogenesis by repressing transposable elements and preventing their mobilization, which is essential for the germline integrity. Plays an essential role in meiotic differentiation of spermatocytes, germ cell differentiation and in self-renewal of spermatogonial stem cells. Its presence in oocytes suggests that it may participate in similar functions during oogenesis in females. 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 govern 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 primary piRNAs in the cytoplasm and is required for PIWIL4/MIWI2 nuclear localization and association with secondary piRNAs antisense. The piR

| Tissue Specificity |
Expressed in adult testis, specifically in spermatocytes and in spermatogonia. Only detected in primordial germ cells of both sexes. Widely expressed in tumors. Also present at early stages of oocyte growth. Expressed in brain (at protein level). {ECO:0000269|PubMed:11279525, ECO:0000269|PubMed:11578866, ECO:0000269|PubMed:12906857, ECO:0000269|PubMed:18404146, ECO:0000269|PubMed:18922463, ECO:0000269|PubMed:19114715, ECO:0000269|PubMed:19377467}.
