Anti-FANCM antibodies are used in the immunodetection of the protein FA complementation group M. In humans, the canonical protein has a reported length of 2048 amino acid residues and a mass of 232.2 kDa. Its subcellular localization is in the nucleus. Up to 3 different isoforms have been reported for this protein. It is reported to be expressed in germ cells of fetal and adult ovaries. It is a member of the DEAD box helicase protein family. Post-translational modifications have been described, including phosphorylation. Synonyms for this target antigen include ATP-dependent RNA helicase FANCM, Fanconi anemia complementation group M, fanconi anemia-associated polypeptide of 250 kDa, protein Hef ortholog, and Fanconi anemia group M protein. FANCM gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. A number of FANCM antibodies have been mentioned in research publications and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
