Anti-prmC antibodies are used in antigen-specific immunodetection in biological samples. The target prmC is a known alias name of the protein N-6 adenine-specific DNA methyltransferase 1, encoded by the N6AMT1 gene in humans. This 214-amino acid residue protein is a reported methyltransferase that can methylate proteins and, to a lower extent, arsenic. It is localized to the nucleus of the cell and features ubiquitinated post-translational modifications. In terms of tissue expression, it is found to be widely expressed, with highest expression in parathyroid and pituitary glands, followed by adrenal gland and kidney, and lowest expression in leukocytes and mammary gland.
