Autophagy of the endoplasmic reticulum (ER), known as ER-phagy, is responsible for the degradation of ER portions by lysosomes. ER-phagy is induced in both physiological and stress conditions to maintain ER homeostasis and protein quality control. ER-phagy receptors and their interactors are key regulators of this process. Transcriptional and post-translational regulation of ER-phagy receptors have emerged as critical mechanisms for the modulation of ER-phagy, providing the first hints to understand how this process responds to the cellular needs. Here, we concisely review the main mechanisms regulating ER-phagy receptors and discuss their potential implications in diseases.
内质网自噬,即内质网吞噬,负责通过溶酶体对内质网部分进行降解。内质网吞噬在生理和应激条件下均会被诱导,以维持内质网稳态和蛋白质质量控制。内质网吞噬受体及其相互作用分子是这一过程的关键调节因子。内质网吞噬受体的转录和翻译后调控已成为调节内质网吞噬的关键机制,为理解这一过程如何响应细胞需求提供了初步线索。在此,我们简要综述调节内质网吞噬受体的主要机制,并讨论它们在疾病中的潜在意义。
