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 [goid 184] [pmid 16488880] [evidence TAS]; 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 [goid 184] [pmid 11544179] [evidence IDA]; 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 [goid 184] [pmid 11331269] [evidence NAS]; The process of restoring DNA after damage. Genomes are subject to damage by chemical and physical agents in the environment (e.g. UV and ionizing radiations, chemical mutagens, fungal and bacterial toxins, etc.) and by free radicals or alkylating agents endogenously generated in metabolism. DNA is also damaged because of errors during its replication. A variety of different DNA repair pathways have been reported that include direct reversal, base excision repair, nucleotide excision repair, photoreactivation, bypass, double-strand break repair pathway, and mismatch repair pathway [goid 6281] [evidence IEA]; The directed movement of mRNA from the nucleus to the cytoplasm [goid 6406] [pmid 16488880] [evidence TAS]; The posttranslational phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine [goid 18105] [pmid 15175154] [evidence IDA]; The posttranslational phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine [goid 18105] [pmid 11544179] [evidence IDA]; The posttranslational phosphorylation of peptidyl-serine to form peptidyl-O-phospho-L-serine [goid 18105] [pmid 14636577] [evidence TAS]; The phosphorylation by a protein of one or more of its own amino acid residues, or residues on an identical protein [goid 46777] [pmid 11544179] [evidence IDA]; The phosphorylation by a protein of one or more of its own amino acid residues, or residues on an identical protein [goid 46777] [pmid 11331269] [evidence IDA]; The process of introducing one or more phosphate groups into a phosphoinositide, a class of substances comprising phosphatidylinositol and its derivatives [goid 46854] [pmid 11331269] [evidence IDA]
