2024年5月7日 · Upon endoplasmic reticulum (ER) stress, activation of the ER-resident transmembrane protein kinase/endoribonuclease inositol-requiring enzyme 1 (IRE1) initiates a key branch of the unfolded...
Targeting IRE1 with small molecules counteracts progression of ... - PNAS
Our findings show that inositol-requiring enzyme 1 (IRE1) plays a critical role in metaflammation and that administering IRE1-specific inhibitors to hyperlipidemic mice counteracts atherosclerosis progression.
IRE1α RIDD activity induced under ER stress drives neuronal death …
2021年6月3日 · Three ER-resident transmembrane proteins orchestrate the UPR: inositol-requiring enzyme 1 (IRE1), activating transcription factor 6 (ATF6), and protein kinase RNA (PKR)-like ER kinase (PERK)....
The Structure, Activation and Signaling of IRE1 and Its Role in ...
Inositol-requiring enzyme type 1 (IRE1) is a serine/threonine kinase acting as one of three branches of the Unfolded Protein Response (UPR) signaling pathway, which is activated upon endoplasmic reticulum (ER) stress conditions.
Targeting IRE1α reprograms the tumor microenvironment and
2024年10月15日 · Single-cell RNA-sequencing analysis reveals that targeting IRE1α in cancer cells reduces tumor-associated macrophage abundance. Consistently, the small molecule IRE1α inhibitor MKC8866, currently...

2024年5月9日 · IRE1是从酵母到哺乳动物保存的最古老的内质网应激传感器,具有一个N端内质网管结构域(LD),用于检测未折叠/错误折叠的蛋白质负载, 一个跨膜段 ...
Protein Disulfide Isomerase A6 Controls the Decay of ... - Cell …
2014年2月20日 · Here, we demonstrate a mechanism that attenuates the activity of the UPR sensor inositol-requiring enzyme 1α (IRE1α). A resident ER protein disulfide isomerase, PDIA6, limits the duration of IRE1α activity by direct binding to cysteine 148 in the lumenal domain of the sensor, which is oxidized when IRE1 is activated.
Nature Metabolism:内质网应激促肥胖?原来是IRE1α在捣乱!
2022年10月28日 · 研究发现内质网应激状态下,IRE1α被激活并诱导XBP-1 mRNA形成剪接形式的XBP-1s,通过直接与ERSE(内质网应激响应元件)相互结合,进一步增强内质网伴侣蛋白基因的转录,以应对内质网应激;另一方面,其RNase活性还可以选择性降解mRNA,这一过程称为RIDD(IRE1α依赖性调节降解)。 有研究发现在损伤诱导的肌肉再生过程中IRE1α高表达,IRE1α通过其RIDD活性下调 Myostatin (肌肉修复和再生的负调控因子)mRNA水平,从而 …
