Anti-P15-2 antibodies enable researchers to detect and measure the P15-2 antigen in biological samples. This target is a reported synonym of the NXT2 gene, which encodes nuclear transport factor 2 like export factor 2. This protein is a reported regulator of protein export for NES-containing proteins. The human version of P15-2 has a canonical amino acid length of 142 residues and a protein mass of 16.2 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and widely expressed in many tissue types.
