Anti-TASL antibodies are used in the immunodetection of the protein TLR adaptor interacting with endolysosomal SLC15A4. In humans, the canonical protein has a reported length of 301 amino acid residues and a mass of 33.9 kDa. Its subcellular localization is in the nucleus, lysosomes and cytoplasm. TASL is known to be involved with innate immune responses. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include 5430427O19Rik, TLR adaptor interacting with SLC15A4 on the lysosome, protein CXorf21, uncharacterized protein CXorf21, and TLR adapter interacting with SLC15A4 on the lysosome. TASL gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species.
