Anti-CD158G antibodies enable researchers to detect and measure the CD158G antigen in biological samples. This target is a reported synonym of the KIR2DS5 gene, which encodes killer cell immunoglobulin like receptor, two Ig domains and short cytoplasmic tail 5. This protein is known to function in immune response pathways, among other biological roles. The human version of CD158G has a canonical amino acid length of 304 residues and a protein mass of 33.7 kilodaltons. It is reported to be localized in the cell membrane of cells. This target antigen may also be known as NKAT9.
