Deficient methylation and formylation of mt-tRNAMet wobble cytosine in a patient lacking NSUN3


30.06.16 - New article from the Frye Lab in Nature Communications

Mitochondrial disease is a chronic, genetic disorder caused by dysfunctional mitochondria, the organelles that generate energy for cells. Researchers used patient cells to identify a novel mechanism causing mitochondria to fail: Loss-of-function mutations in an enzyme called NSUN3 prevents the synthesis of proteins in mitochondria, and thereby leaving them non-functional.
