生化/生理作用
4μ8C 是 ER 跨膜蛋白 IRE1 的强效抑制剂。
4μ8C 是内质网跨膜蛋白 IRE1 的强效抑制剂，介导未折叠蛋白反应。4μ8C 抑制调节的 IRE1 依赖性降解 (RIDD) 和 XBP1 mRNA 对内质网 (ER) 应激的非常规剪接，但对 IRE1 的激酶活性没有影响。
4μ8C 是水杨醛衍生物，其抑制作用靶向 RNase（核糖核酸酶）结构域中的 K907 赖氨酸残基，影响 IRE1αRNase 活性。体外 分析证明 4μ8C 能够在高糖水平抑制胰岛素的释放。

Aneuploidy is a chromosomal abnormality associated with poor prognosis in many cancer types. Here, we tested the hypothesis that the unfolded protein response (UPR) mechanistically links aneuploidy and local immune dysregulation. Using a single somatic copy number alteration (SCNA) score

The kinase/endonuclease IRE1 is the most conserved signal transducer of the unfolded protein response (UPR), an intracellular signaling network that monitors and regulates the protein folding capacity of the endoplasmic reticulum (ER). Upon sensing protein folding perturbations in the ER
