Quality Control in the Endoplasmic Reticulum: Crosstalk between ERAD ...
Endoplasmic reticulum (ER)-associated degradation (ERAD) and the unfolded protein response (UPR) are two key quality-control machineries in the cell. ERAD is responsible for the clearance of misfolded proteins in the ER for cytosolic proteasomal degradation, while UPR is activated in response to the …
什么是内质网相关降解(ERAD)?国自然开始了,研究一下!
在ERAD过程中,待降解的底物(分三种:ERAD-L (lumen)、ERAD-M (membrane)和ERAD-C (cytosol))通过E3连接酶标记上泛素,之后,通过特定的运输机制运回到细胞质中,然后,被细胞质26S蛋白酶体所降解。

erad 是为了维持内质网的稳态而存在的错误折叠蛋白降解系统。 所有的真核生物都有内质网蛋白质控系统(ERQC)去识别错误蛋白,避免缺陷蛋白的释放。
Nat Cell Biol: 内质网相关RNA沉默(ERAS)的发现 - 知乎
在介绍这篇文章之前首先要来说一说UPR和 ERAD /ERQC。 UPR: 未折叠蛋白反应 (unfolded protein response); ERAD:内质网相关蛋白降解(ER-associated degradation); ERQC: 内质网质控 (ER quality control)。 UPR的机理在细胞生物学的课程中就说过,没有学过的读者也不用担 …
内质网质量控制:ERAD 和 UPR 通路之间的串扰,Trends in …
内质网 (er) 相关降解 (erad) 和未折叠蛋白反应 (upr) 是细胞中两个关键的质量控制机制。erad 负责清除 er 中错误折叠的蛋白质以进行细胞溶质蛋白酶体降解,而 upr 则响应错误折叠蛋白质的积累而被激活。

The Unfolded Protein Response: An Overview - PMC
The unfolded protein response (UPR) is the cells’ way of maintaining the balance of protein folding in the endoplasmic reticulum, which is the section of the cell designated for folding proteins with specific destinations such as other organelles or to be secreted by the cell.
