Target

  • FunctionInvolved in pre-rRNA processing. Utilizes the methyl donor S-adenosyl-L-methionine to catalyze the site-specific 2'-hydroxyl methylation of ribose moieties in pre-ribosomal RNA. Site specificity is provided by a guide RNA that base pairs with the substrate. Methylation occurs at a characteristic distance from the sequence involved in base pairing with the guide RNA.
  • Sequence similaritiesBelongs to the methyltransferase superfamily. Fibrillarin family.
  • Post-translational
    modifications
    By homology to other fibrillarins, some or all of the N-terminal domain arginines are modified to asymmetric dimethylarginine (DMA).
  • Cellular localizationNucleus > nucleolus. Fibrillar region of the nucleolus.
