Anti-NKAT9 antibodies are used in antigen-specific immunodetection in biological samples. The target NKAT9 is a known alias name of the protein killer cell immunoglobulin like receptor, two Ig domains and short cytoplasmic tail 5, encoded by the KIR2DS5 gene in humans. This 304-amino acid residue protein is known to be involved in immune response pathways, among other biological processes. It is localized to the cell membrane of the cell and features N-glycosylated post-translational modifications. In terms of tissue expression, it is noted to be expressed on a discrete subset of peripheral blood NK cells. Other synonyms for NKAT9 include CD158G and CD158G.
