Anti-killer cell immunoglobulin like receptor, two Ig domains and short cytoplasmic tail 5 antibodies are used for the immunodetection of the protein encoded by the KIR2DS5 gene. In humans, the canonical protein has a reported length of 304 amino acid residues and a mass of 33.7 kDa. Its subcellular localization is in the cell membrane. It is noted to be expressed on a discrete subset of peripheral blood NK cells. A member of the Immunoglobulin protein superfamily, it is known to be involved with immune response pathways. Post-translational modifications have been described, including N-glycosylation. Other names for this target antigen include NKAT9, killer cell immunoglobulin-like receptor 2DS5, CD158 antigen-like family member G, NKAT-9, and CD158G. Over 120 citations in the literature describe the use of killer cell immunoglobulin like receptor, two Ig domains and short cytoplasmic tail 5 antibodies in research. These antibodies are most commonly used in Flow Cytometry experiments, among other applications.
