Anti-KIR2DL5 antibodies enable researchers to detect and measure the KIR2DL5 antigen in biological samples. This target is a reported synonym of the KIR2DL5B gene, which encodes killer cell immunoglobulin like receptor, two Ig domains and long cytoplasmic tail 5B. This protein is a known receptor on natural killer (NK) cells for HLA-C alleles. The human version of KIR2DL5 has a canonical amino acid length of 375 residues and a protein mass of 40.7 kilodaltons. It is reported to be localized in the cell membrane of cells. KIR2DL5 is a member of the Immunoglobulin protein superfamily.
