Anti-oligonucleotide/oligosaccharide binding fold containing 1 antibodies enable researchers to detect and measure the oligonucleotide/oligosaccharide binding fold containing 1 antigen in biological samples. This target is a reported synonym of the STN1 gene, which encodes STN1 subunit of CST complex. This protein is known to function in DNA replication and DNA repair, among other biological roles. The human version of oligonucleotide/oligosaccharide binding fold containing 1 has a canonical amino acid length of 368 residues and a protein mass of 42.1 kilodaltons. It is reported to be localized in the nucleus of cells. Other names for this target antigen include CST complex subunit STN1, STN1, CST complex subunit, and alpha accessory factor 44.
