Anti-neuregulin 2 antibodies are used for the immunodetection of the protein encoded by the NRG2 gene. 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. Alternative splicing is reported to yield 8 different isoforms for this protein. A member of the Neuregulin protein family, it is known to be involved with intracellular signal transduction and nervous system development. Post-translational modifications have been described, including glycosylation and protein cleavage. Other names 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. Gene orthologs have been identified in the mouse, rat, bovine, chimpanzee and chicken species. Some neuregulin 2 antibodies may have been used in research and have associated citations. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
