Anti-neuregulin 4 antibodies are used for the immunodetection of the protein encoded by the NRG4 gene. In humans, the canonical protein has a reported length of 115 amino acid residues and a mass of 12.7 kDa. Its subcellular localization is in the cell membrane. A member of the Neuregulin protein family, it is known to be involved with nervous system development. Post-translational modifications have been described, including glycosylation and protein cleavage. Other names for this target antigen include heregulin 4, pro-NRG4, and pro-neuregulin-4, membrane-bound isoform. Gene orthologs have been identified in the mouse, rat, chimpanzee and chicken species. Some neuregulin 4 antibodies may have been used in research and have associated citations. ELISA is a widely used application for these antibodies. Western Blot and Immunohistochemistry are also common applications.
