Anti-MRNIP antibodies are used in the immunodetection of the protein MRN complex interacting protein. In humans, the canonical protein has a reported length of 343 amino acid residues and a mass of 37.7 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. A member of the MRNIP protein family, MRNIP is reported to play a role in the cellular response to DNA damage and the maintenance of genome stability through its association with the MRN damage-sensing complex. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include MRN-interacting protein, UPF0544 protein C5orf45, and C5orf45. MRNIP gene orthologs have been reported in the mouse, rat, bovine, zebrafish, chimpanzee and chicken species. Some MRNIP antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
