  Function in Host
DNA-dependent RNA polymerase catalyzes the transcription ofDNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase I which synthesizes ribosomal RNAprecursors. Appears to be involved in the formationof the initiation complex at the promoter by mediating the interactionbetween Pol I and UBTF/UBF. [1]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Anti-viral [2]
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 POLR1E in viral infection, POLR1E 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 POLR1E increases SARS-CoV-2 RNA levels compared with control group.
