Function
RS27_RABIT Component of the small ribosomal subunit (PubMed:23873042, PubMed:25601755, PubMed:26245381, PubMed:27863242). The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell (PubMed:23873042, PubMed:25601755, PubMed:26245381, PubMed:27863242). Required for proper rRNA processing and maturation of 18S rRNAs (PubMed:23873042, PubMed:25601755, PubMed:26245381, PubMed:27863242). Part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit (PubMed:23873042, PubMed:25601755, PubMed:26245381, PubMed:27863242). 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 (By similarity).[UniProtKB:P42677][1] [2] [3] [4]
