Anti-TLR7 antibodies are used in the immunodetection of the protein toll like receptor 7. In humans, the canonical protein has a reported length of 1049 amino acid residues and a mass of 120.9 kDa. Its subcellular localization is in the ER, lysosomes, and cytoplasmic vesicles. It is notably expressed in the brain, placenta, spleen, stomach, small intestine, lung and in plasmacytoid pre-dendritic cells. A member of the Toll-like receptor protein family, TLR7 is reported to be an endosomal receptor that plays a key role in innate and adaptive immunity. Post-translational modifications have been described, including glycosylation. TLR7 is also used as a cellular marker for characterizing granulocytes. Synonyms for this target antigen include SLEB17, TLR7-like, toll-like receptor 7-like, and IMD74. TLR7 gene orthologs have been reported in the mouse, rat, bovine, frog and chimpanzee species.
