Regulator of nonsense transcripts 1 is a protein that in humans is encoded by the UPF1 gene.[5][6]
Function
This gene encodes a protein that is part of a post-splicing multiprotein complex, the
nonsense-mediated mRNA decay (NMD). When translation ends upstream from the last exon-exon junction, this triggers NMD to degrade mRNAs containing premature stop codons. This protein is located in both the cytoplasm and nucleus of the cell.[7] When translation ends, it interacts with the protein that is a functional homolog of yeast Upf2p to trigger mRNA decapping. Use of multiple polyadenylation sites has been noted for this gene.[8]
