Anti-Forkhead Box M1 antibodies are used for the immunodetection of the protein encoded by the FOXM1 gene. In humans, the canonical protein has a reported length of 763 amino acid residues and a mass of 84.3 kDa. Its subcellular localization is in the nucleus. Alternative splicing is reported to yield 3 different isoforms for this protein. It is reported to be expressed in thymus, testis, small intestine, colon followed by ovary. It is reported to be a transcription factor regulating the expression of cell cycle genes essential for DNA replication and mitosis. Post-translational modifications have been described, including phosphorylation. Other names for this target antigen include FOXM1A, FOXM1B, FOXM1C, HFH-11, HFH11, HNF-3, INS-1, and FKHL16. Gene orthologs have been identified in the mouse, rat, bovine, frog, zebrafish and chimpanzee species. Over 410 citations in the literature describe the use of Forkhead Box M1 antibodies in research. Western Blot is a widely used application for these antibodies. In addition, ELISA is also a common application.
