Protein Name:
Small subunit processome component 20 homolog
|
UniprotKB/SwissProt ID: O75691 (O75691)
Gene Name:
UTP20
Organism: Homo sapiens (Human)
Function: 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. Involved in 18S pre-rRNA processing. Associates with U3 snoRNA

Protein Subcellular Localization: Nucleus, nucleolus
