Anti-CD337 antibodies enable researchers to detect and measure the CD337 antigen in biological samples. This target is a reported synonym of the NCR3 gene, which encodes natural cytotoxicity triggering receptor 3. This protein is known to function in immune response pathways and inflammatory response pathways, among other biological roles. The human version of CD337 has a canonical amino acid length of 201 residues and a protein mass of 21.6 kilodaltons, although 6 isoforms have been identified. It is reported to be localized in the cell membrane of cells. CD337 is a member of the Natural cytotoxicity receptor (NCR) protein family.
