Ser(Thr)-O-linked beta-N-acetylglucosamine (O-GlcNAc) is a ubiquitous modification of nucleocytoplasmic proteins. Extensive crosstalk exists between O-GlcNAcylation and phosphorylation, which regulates signaling in response to nutrients/stress. The development of novel O-GlcNAc detection and enrichment methods has improved our understanding of O-GlcNAc functions. Mass spectrometry has revealed O-GlcNAc's many interactions with phosphorylation-mediated signaling. However, mechanisms regulating O… CONTINUE READING
