Regulatory events controlling ER-phagy

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.
