摘要: 葡萄糖调节蛋白78(GRP78),又称为免疫结合球蛋白(Bip),是细胞应激时产生的应激蛋白。作为热休克蛋白70家族的一员,在应激条件下,GPR78蛋白通过在内质网中协助多聚体蛋白质复合物的形成,起到保护和维持细胞正常代谢作用。肝脏是机体物质代谢的重要器官,各种酶和蛋白的生化加工厂,故应激反应下肝细胞GRP78/ Bip的表达显得尤为重要。

Abstract: Glucose regulated protein78,GRP78,called immunoglobulin binding protein, is a highly conserved stress protein which is produced by the organism in the stressor stimulation. GRP-78 protein appears to play a role in helping in the assembly of multimeric proteincomplexes in the endoplasmic reticulum (ER).The expression of GRP78/Bip plays a particularly vital role of dealing with the stress response in the liver which is important organ of the body metabolismand biochemical processing factory of various enzyme.
Key words: Glucose regulated protein78, liver, Heat Stress, Oxidative Stress, Endoplasmic Reticulum Stress
