Comments
  • FUNCTION: Component of a nucleolar small nuclear ribonucleoprotein particle (snoRNP) thought to participate in the processing and modification of pre-ribosomal RNA.
  • SUBUNIT: Interacts specifically with the U3 small nucleolar RNA (U3 snoRNA). Binds a sub-fragment of the U3 snoRNA surrounding the B/C motif (3UBC). This association with the U3BC RNA is dependent on the binding of a protein called 15.5K to the box B/C motif. The association of the protein with the U3BC RNA was found to be also dependent on a conserved RNA structure that flanks the box B/C motif.
  • SUBCELLULAR LOCATION: Nucleus, nucleolus.
  • DOMAIN: The WD domains are required for nucleolar localization and U3 small nucleolar RNAs binding.
  • SIMILARITY: Belongs to the WD repeat RRP9 family.
  • SIMILARITY: Contains 7 WD repeats.
