Background InformationrRNA 2'-O-methyltransferase fibrillarin (UniProt: P15646; also known as Histone-glutamine methyltransferase, U3 small nucleolar RNA-associated protein NOP1, Nucleolar protein 1, U3 snoRNA-associated protein NOP1) is encoded by the NOP1 (also known as LOT3, YDL014W, D2870) gene (Gene ID: 851548) in yeast. Fibrillarin is a nucleolar protein that is highly conserved throughout evolution. Human fibrillarin is 67% identical to its yeast homolog Nop1p. Fibrillarin is a protein component of C/D box small nucleolar ribonucleoproteins (snoRNPs) that direct 2 -O-methylation of rRNA and is also involved in other aspects of rRNA processing. Unlike snRNAs, which have a cytoplasmic phase of maturation, snoRNAs are restricted to the nucleus. Fibrillarin is essential for yeast viability and fibrillarin knockout is shown to be lethal in S. cerevisiae; however, expression of human or Xenopus fibrillarin overcome this lethality. The first 80 amino acids from the N terminal region of fibrillarin contain multiple RGG, or arginine-glycine-glycine (GAR). The remaining ~240 amino acids consist of the so called fibrillarin domain. NOP1 depleted strains of yeast are greatly impaired in the production of cytoplasmic ribosomes, and they have a reduced level of rRNA. Patients with scleroderma are reported to have strong circulating autoantibodies to fibrillarin. (Ref.: Tollervey, D et al. (1991). EMBO J. 10(3):573-83; Newton, K et al. (2003). Mol. Cell. Biol. 23(23): 8519-8527).
