ABSTRACT

Unlike prokaryotes, N-terminal formylation has been confined to a handful of mitochondrial proteins in eukaryotes. A recent study unveils a new role for eukaryotic cytoplasmic N-terminal formylation linking diverse cellular stresses to N-terminal-dependent protein degradation. These findings suggest broad cellular implications in higher eukaryotes for N-terminal methionine formylation.
