SYVN1 and infection: In addition to having found that factors involved in proteasomal ERAD, such as HRD1 and EDEM1, are enriched at the UL148 structures, we observed that GABARAP, a mammalian ortholog of yeast ATG8, localizes to the UL148 ER structures during infection and that GABARAP and another ATG8 ortholog, LC3B, both associate with the structures during ectopic expression of UL148.
