Known also as: RRP9 homolog, U3 small nucleolar ribonucleoprotein-associated 55 kDa protein
Known abbreviations: RRP9, 15.5K
Component of a nucleolar small nuclear ribonucleoprotein particle (snoRNP) thought to participate in the processing and modification of pre-ribosomal RNA.
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.
Nucleus › nucleolus.
The WD domains are required for nucleolar localization and U3 small nucleolar RNAs binding.
Belongs to the WD repeat RRP9 family.
Contains 7 WD repeats.
