Anti-NKG2F antibodies enable researchers to detect and measure the NKG2F antigen in biological samples. This target is a reported synonym of the KLRC4 gene, which encodes killer cell lectin like receptor C4. This protein is believed to play a role as a receptor for the recognition of MHC class I HLA-E molecules by NK cells. The human version of NKG2F has a canonical amino acid length of 158 residues and a protein mass of 18.2 kilodaltons. It is reported to be localized in the membrane of cells.
