Senecavirus a 3C protease cleaves RETREG1 to antagonize ER-phagy and promote viral replication via endoplasmic reticulum calcium signaling.
Co-evolution between viruses and autophagy has led to the emergence of viral strategies that manipulate host endoplasmic reticulum (ER) homeostasis, ultimately promoting viral replication. ER turnover is achieved through selective autophagy, also referred to as ER-phagy, which is regulated by the RETREG1/FAM134B (retic...
