Summary
{"type": "root", "children": [{"type": "p", "children": [{"type": "t", "text": "\nERI1 is an evolutionarily conserved exoribonuclease that plays a key regulatory role in RNA interference. In Caenorhabditis elegans, loss‐of-function mutations in eri-1 result in the accumulation of small interfering RNAs (siRNAs) following double-stranded RNA exposure, indicating that ERI1 normally degrades siRNAs to limit or fine-tune RNA interference responses. This negative regulation appears to control the duration, cell-type specificity, or endogenous functions of RNA silencing mechanisms in vivo."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nBiochemical and structural studies of the related human 3′-5′ exonuclease (3′hExo)—for which ERI1 is the Caenorhabditis elegans orthologue—further underscore the RNA specificity of this enzyme. Mutational analyses have demonstrated that its nucleic-acid-binding domain and exonuclease motifs are crucial for recognizing the unique structural features of target RNAs and for digesting their 3′ overhangs.
