  Function in Host
Disulfide isomerase which catalyzes the formation, isomerization, and reduction or oxidation of disulfide bonds. Associates with calcitriol, theactive form of vitamin D3 which mediates the action of this vitamin oncells. Association with calcitriol does not affectits enzymatic activity. [1-2]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Pro-viral [3]
Infected TissueLung Infection Time7-9 Days
Infected CellCalu-3 Cells (Human epithelial cell line) Cellosaurus IDCVCL_0609 
Method DescriptionTo detect the role of host protein PDIA3 in viral infection, PDIA3 protein knockout Calu-3 Cells were infected with SARS-COV-2 for 7 - 9 Days , and the effects on infection was detected through CRISPR-based genome-wide gene-knockout screen.
ResultsIt is reported that knockout of PDIA3 leads to the decreased SARS-CoV-2 RNA levels compared with control group.
