Anti-PIWIL3 antibodies are used in the immunodetection of the protein piwi like RNA-mediated gene silencing 3. In humans, the canonical protein has a reported length of 882 amino acid residues and a mass of 101.1 kDa. Its subcellular localization is in the cytoplasm. It is notably expressed in the testis. A member of the Argonaute protein family, PIWIL3 is believed to play a role during spermatogenesis by repressing transposable elements and preventing their mobilization, which is essential for the germline integrity. Synonyms for this target antigen include piwi-like protein 3 and piwi-like 3. PIWIL3 gene orthologs have been reported in the mouse, bovine and chimpanzee species. Some PIWIL3 antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunofluorescence are also common applications.
