Anti-SLC9A3 regulator 2 antibodies enable researchers to detect and measure the SLC9A3 regulator 2 antigen in biological samples. This target is a reported synonym of the NHERF2 gene, which encodes NHERF family PDZ scaffold protein 2. This protein is known to function in protein localization to the plasma membrane and the assembly of protein complexes, among other biological roles. The human version of SLC9A3 regulator 2 has a canonical amino acid length of 337 residues and a protein mass of 37.4 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus and cell membrane of cells. Other names for this target antigen include E3KARP, NHE3RF2, and OCTS2. A number of SLC9A3 regulator 2 antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. ELISA and Immunohistochemistry are also common applications.
