Summary	Endoribonuclease that plays a central role in postnatal germ cells by repressing transposable elements and preventing their mobilization, which is essential for the germline integrity (PubMed:11578866, PubMed:22121019, PubMed:21237665). 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 (PubMed:11578866, PubMed:22121019, PubMed:21237665). Directly binds methylated 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 (PubMed:11578866, PubMed:22121019, PubMed:21237665). Strongly prefers a uridine in the first position of their guide (g1U preference, also named 1U-bias) (PubMed:24757166). Not involved in the piRNA amplification loop, also named ping-pong amplification cycle (PubMed:22121019). Acts as an endoribonuclease that cleaves transposon messenger RNAs (PubMed:22121019). Besides their function in transposable elements repression, piRNAs are probably involved in other processes during meiosis such as translation regulation (PubMed:16938833). Probable component of some RISC complex, which mediates RNA cleavage and translational silencing (PubMed:16938833). Also plays a role in the formation of chromatoid bodies and is required for some miRNAs stability (PubMed:16787948). Required to sequester RNF8 in the cytoplasm until late spermatogenesis; RNF8 being released upon ubiquitination and degradation of PIWIL1 (PubMed:28552346).[UniProtKB/Swiss-Prot Function]
Performance Guranteed	OriGene guarantees that at least two of the three Dicer-Substrate duplexes in the kit will provide at least 70% or more knockdown of the target mRNA when used at 10 nM concentration by quantitative RT-PCR when the TYE-563 fluorescent transfection control duplex (cat# SR30002) indicates that >90% of the cells have been transfected and the HPRT positive control (cat# SR30003) provides 90% knockdown efficiency. For non-conforming siRNA, requests for replacement product must be made within ninety (90) days from the date of delivery of the siRNA kit. To arrange for a free replacement with newly designed duplexes, please contact Technical Services at techsupport@origene.com. Please provide your data indicating the transfection efficiency and measurement of gene expression knockdown compared to the scrambled siRNA control (quantitative RT-PCR data required).
