[[http://www.uniprot.org/uniprot/U3KPD5_RABIT U3KPD5_RABIT]] Binds to the 23S rRNA.[RuleBase:RU000576] [[http://www.uniprot.org/uniprot/ERF1_HUMAN ERF1_HUMAN]] Directs the termination of nascent peptide synthesis (translation) in response to the termination codons UAA, UAG and UGA. Component of the transient SURF complex which recruits UPF1 to stalled ribosomes in the context of nonsense-mediated decay (NMD) of mRNAs containing premature stop codons.<ref>PMID:7990965</ref> [[http://www.uniprot.org/uniprot/G1SS70_RABIT G1SS70_RABIT]] May play a role during erythropoiesis through regulation of transcription factor DDIT3.[HAMAP-Rule:MF_03122]
[https://www.uniprot.org/uniprot/RS5_RABIT RS5_RABIT] Component of the small ribosomal subunit (PubMed:23873042, PubMed:25601755, PubMed:27863242, PubMed:30517857). The ribosome is a large ribonucleoprotein complex responsible for the synthesis of proteins in the cell (PubMed:23873042, PubMed:25601755, PubMed:27863242, PubMed:30517857). Part of the small subunit (SSU) processome, first precursor of the small eukaryotic ribosomal subunit (PubMed:23873042, PubMed:25601755, PubMed:27863242, PubMed:30517857). 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:P46782]<ref>PMID:23873042</ref> <ref>PMID:25601755</ref> <ref>PMID:27863242</ref> <ref>PMID:30517857</ref>
