Anti-RNMT antibodies are used in the immunodetection of the protein RNA guanine-7 methyltransferase. In humans, the canonical protein has a reported length of 476 amino acid residues and a mass of 54.8 kDa. Its subcellular localization is in the nucleus. Up to 2 different isoforms have been reported for this protein. It is widely expressed across many tissue types. A member of the mRNA cap 0 methyltransferase protein family, RNMT is a known catalytic subunit of the mRNA-capping methyltransferase RNMT:RAMAC complex that methylates the N7 position of the added guanosine to the 5'-cap structure of mRNAs. Synonyms for this target antigen include CMT1c, MET, N7-MTase, RG7MT1, cm1p, hCMT1, hMet, and CMT1. RNMT gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Some RNMT antibodies may have been used in research and have associated citations. Western Blot is a widely used application for these antibodies. Immunofluorescence and Immunohistochemistry are also common applications.
