Anti-Misu antibodies are used in antigen-specific immunodetection in biological samples. The target Misu is a known alias name of the protein NOP2/Sun RNA methyltransferase 2, encoded by the NSUN2 gene in humans. This 767-amino acid residue protein is known to be involved in cell division and in utero embryonic development, among other biological processes. It is localized to the nucleus, mitochondria, and cytoplasm of the cell and features phosphorylated post-translational modifications. In terms of tissue expression, it is reported to be expressed in adult and fetal brain and in lymphoblastoid cells. Other synonyms for Misu include MRT5 and SAKI.
