High impact information on SOF1

  • Thus, SOF1 is a new component of the nucleolar rRNA processing machinery [1].
  • In its central domain, SOF1 contains a repeated sequence also found in beta-subunits of trimeric G-proteins and the splicing factor PRP4 [1].
  • The wild-type allele of SOF1 is essential for cell growth and encodes a novel 56 kDa protein [1].
  • Finally, we found that an overall reduction in the levels of box C/D snoRNPs by genetic depletion of the common Nop58p protein did not affect coprecipitation of 35S pre-rRNA by Sof1p [2].
  • Sof1p is a trans-acting protein that is essential for biogenesis of the 40S ribosomal subunits in the yeast Saccharomyces cerevisiae [2].
