内质网在动植物中分布广泛,功能多样,它既是所有生物膜的来源;又是细胞钙离子的存储库,对细胞内钙信号起调节作用。它对分泌蛋白的质量进行严格的控制,新生蛋白只有经过信号肽切除、N糖基化、二硫键的正确连接才能形成正确的空间结构,在此过程中分子伴侣发挥了重要作用[1]。当未折叠或错误折叠蛋白质在内质网中累积,或细胞内钙稳态失衡时, Endoplasmic reticulum in animal and plant widely distributed, diverse functions, it is not only the source of all biofilms; is also a repository of cellular calcium ions, the regulation of intracellular calcium signals. It controls the quality of the secretory protein strictly. The nascent protein can form the correct spatial structure only through the signal peptide excision, N-glycosylation, and the correct connection of the disulfide bond. In this process, the chaperone plays an important role [1] . When unfolded or misfolded proteins accumulate in the endoplasmic reticulum, or the intracellular calcium homeostasis is out of balance,
