Anti-C17orf74 antibodies enable researchers to detect and measure the C17orf74 antigen in biological samples. This target is a reported synonym of the SPEM2 gene, which encodes SPEM family member 2. The human version of C17orf74 has a canonical amino acid length of 501 residues and a protein mass of 57.1 kilodaltons. It is reported to be localized in the membrane of cells.
