Protein Name: U3 small nucleolar RNA-interacting protein 2

UniprotKB/SwissProt ID: O43818 (O43818)

Gene Name: RRP9

Organism: Homo sapiens (Human)

Function: Component of a nucleolar small nuclear ribonucleoprotein particle (snoRNP) thought to participate in the processing and modification of pre-ribosomal RNA (pre-rRNA) (PubMed:26867678). Part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit. During the assembly of the SSU processome in the nucleolus, many ribosome biogenesis factors, an RNA chaperone and ribosomal proteins associate with the nascent pre-rRNA and work in concert to generate RNA folding, modifications, rearrangements and cleavage as well as targeted degradation of pre-ribosomal RNA by the RNA exosome (PubMed:34516797)

Protein Subcellular Localization: Nucleus, nucleolus
