O-GlcNAc modification prevents peptide-dependent acceleration of α-synuclein aggregation.

Abstract

Sweet relief: the Parkinson's disease- associated protein α-synuclein is post-translationally modified by N-acetylglucosamine (O-GlcNAc), but the biochemical consequences are unknown. Here we show that an O-GlcNAc-modified peptide does not participate in α-synuclein aggregation, thus suggesting that O-GlcNAc might directly inhibit aggregation in cells.
