EOG8QFZWD GO:0000184 5/81 nuclear-transcribed mRNA catabolic process, nonsense-mediated decay biological_process "The nonsense-mediated decay pathway for nuclear-transcribed mRNAs degrades mRNAs in which an amino-acid codon has changed to a nonsense codon; this prevents the translation of such mRNAs into truncated, and potentially harmful, proteins." [GOC:krc, GOC:ma, PMID:10025395] EOG8QFZWD GO:0035145 5/81 exon-exon junction complex cellular_component "A multi-subunit complex deposited by the spliceosome upstream of messenger RNA exon-exon junctions. The exon-exon junction complex provides a binding platform for factors involved in mRNA export and nonsense-mediated mRNA decay."
