Anti-neuregulin 3 antibodies are used for the immunodetection of the protein encoded by the NRG3 gene. In humans, the canonical protein has a reported length of 720 amino acid residues and a mass of 77.9 kDa. Its subcellular localization is in the cell membrane. Alternative splicing is reported to yield 4 different isoforms for this protein. It is reported to be highly expressed in most regions of the brain with the exception of corpus callosum. A member of the Neuregulin protein family, it is known to be involved with intracellular signal transduction. Other names for this target antigen include pro-NRG3, pro-neuregulin-3, membrane-bound isoform, neuregulin-3-like polypeptide, and HRG3. Gene orthologs have been identified in the mouse, rat, bovine, frog, chimpanzee and chicken species. A number of neuregulin 3 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.
