The endoplasmic reticulum (ER) is essential for protein synthesis and calcium storage within cells. Its integrity is critical for maintaining cellular homeostasis.
When sections of the ER become damaged, cells utilize a process known as ER-phagy to eliminate these compromised regions. This process involves the formation of double-membrane vesicles called autophagosomes.
The findings emphasize the importance of autophagosomes in the selective degradation of damaged ER, thereby ensuring continued protein synthesis and calcium regulation.
