Anti-CHTOP antibodies are used in the immunodetection of the protein chromatin target of PRMT1. In humans, the canonical protein has a reported length of 248 amino acid residues and a mass of 26.4 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 an erythroid progenitor cell line derived from peripheral blood. CHTOP is known to play an important role in the ligand-dependent activation of estrogen receptor target genes. Post-translational modifications have been described, including methylation. Synonyms for this target antigen include C1orf77, FL-SRAG, FOP, SRAG, SRAG-3, SRAG-5, pp7704, and C10orf77. CHTOP gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some CHTOP antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunocytochemistry, Immunofluorescence, and Immunohistochemistry are also common applications.
