Finding the missing link between the unfolded protein response and O-GlcNAcylation in the heart

Circ Res. 2014 Aug 29;115(6):546-8. doi: 10.1161/CIRCRESAHA.114.304855.

Abstract

The ER stress-inducible transcription factor, x-box binding protein 1 (XBP1), which enhances protein glycosylation in the endoplasmic reticulum (ER), was shown to also enhance protein glycosylation outside the ER, via a process called O-GlcNAcylation, which protected the heart from ischemia/reperfusion damage.
