“Nonsense-mediated mRNA decay: A cellular quality control pathway for aberrant RNA”

In eukaryotic cells, mRNA harboring a premature translation termination codon is recognized and rapidly degraded by a conserved quality control process referred to as the nonsense-mediated mRNA decay (NMD) pathway. NMD represents an important cellular surveillance system that maintains fidelity in gene expression by preventing the accumulation of truncated polypeptides. The molecular mechanisms allowing for discrimination between mRNAs that terminate translation prematurely from those subject to termination at natural stop codons remain unclear. Our research couples biochemical, genetic and molecular biological analyses with whole cell gene expression profiling to further our goal of elucidating how RNA in cells is recognized and targeted by the NMD pathway.

School of Biological Sciences Seminar Series

The School of Biological Sciences Seminar is a weekly series presented by invited speakers and UNL faculty to showcase current research advances in biological sciences. All School of Biological Sciences Seminars are free and open to the public.
