Anti-oligonucleotide/oligosaccharide-binding fold containing 2A antibodies enable researchers to detect and measure the oligonucleotide/oligosaccharide-binding fold containing 2A antigen in biological samples. This target is a reported synonym of the NABP1 gene, which encodes nucleic acid binding protein 1. This protein is known to function in DNA damage pathways and DNA repair, among other biological roles. The human version of oligonucleotide/oligosaccharide-binding fold containing 2A has a canonical amino acid length of 204 residues and a protein mass of 22.4 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus of cells. Other names for this target antigen include SOSS complex subunit B2, NABP1 3'UTR overlapping transcript 1, and lncRNA AK130181.
