    Summary
    Predicted to enable RNA endonuclease activity; mRNA binding activity; and piRNA binding activity. Predicted to be involved in several processes, including germ-line stem cell population maintenance; negative regulation of circadian rhythm; and regulation of gene expression. Predicted to act upstream of with a positive effect on piRNA-mediated retrotransposon silencing by heterochromatin formation. Predicted to act upstream of or within positive regulation of meiosis I. Predicted to be located in cytoplasmic ribonucleoprotein granule; dense body; and perinucleolar chromocenter. Predicted to be part of PET complex. Predicted to be active in P granule and nucleus. Orthologous to human PIWIL2 (piwi like RNA-mediated gene silencing 2). [provided by Alliance of Genome Resources, Dec 2024]

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
