O-GlcNAc is a common post-translational modification of nuclear, mitochondrial, and cytoplasmic proteins that is implicated in the etiology of type II diabetes and Alzheimer's disease, as well as cardioprotection. This unit covers simple and comprehensive techniques for identifying proteins modified by O-GlcNAc, studying the enzymes that add and remove O-GlcNAc, and mapping O-GlcNAc modification sites.
O-连接的N-乙酰葡糖胺(O-GlcNAc)是一种常见的对细胞核、线粒体及细胞质蛋白进行的翻译后修饰,它与II型糖尿病和阿尔茨海默病的病因以及心脏保护作用有关。本单元涵盖了用于鉴定被O-GlcNAc修饰的蛋白、研究添加和去除O-GlcNAc的酶以及定位O-GlcNAc修饰位点的简单和综合技术。
