Anti-NRG2 antibodies are used in the immunodetection of the protein neuregulin 2. In humans, the canonical protein has a reported length of 850 amino acid residues and a mass of 91.7 kDa. Its subcellular localization is in the cell membrane. Up to 8 different isoforms have been reported for this protein. It is notably expressed in many tissues, such as the cervix, vagina, and bronchus. A member of the Neuregulin protein family, NRG2 is known to be involved with intracellular signal transduction and nervous system development. Post-translational modifications have been described, including glycosylation and protein cleavage. Synonyms for this target antigen include HRG2, NTAK, pro-neuregulin-2, membrane-bound isoform, divergent of neuregulin-1, neural- and thymus-derived activator for ErbB kinases, and DON1. NRG2 gene orthologs have been reported in the mouse, rat, bovine, chimpanzee and chicken species. Some NRG2 antibodies may have been used in research and have associated citations. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
