  • Title: CCPG1 is a noncanonical autophagy cargo receptor essential for reticulophagy and pancreatic ER proteostasis.
    Author: Lahiri V, Klionsky DJ.
    Journal: Autophagy; 2018; 14(7):1107-1109. PubMed ID: 29911925.
    Abstract:
    Reticulophagy is the conserved macroautophagic/autophagic degradation of the endoplasmic reticulum (ER) in response to ER stress or general nutrient deprivation. Sequestration of the ER by phagophores plays an important role in regulating ER size and homeostasis. In their recent work, Smith et al. have discovered that the ER-localized protein CCPG1 is a novel mammalian reticulophagy receptor that interacts with core autophagy machinery components-LC3, GABARAP and RB1CC1-and regulates reticulophagy.
