  Function in Host
DNA-dependent RNA polymerase catalyzes the transcription ofDNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase II which synthesizes mRNA precursors andmany functional non-coding RNAs. Pol II is the central component of thebasal RNA polymerase II transcription machinery. It is composed ofmobile elements that move relative to each other. RPB7 is part of asubcomplex with RPB4 that binds to a pocket formed by RPB1, RPB2 andRPB6 at the base of the clamp element. The RBP4-RPB7 subcomplex seemsto lock the clamp via RPB7 in the closed conformation thus preventingdouble-stranded DNA to enter the active site cleft. The RPB4-RPB7subcomplex binds single-stranded DNA and RNA. BindsRNA. [1]

Function of This Protein During Virus Infection
Virus NameSARS-COV-2 Protein Function Pro-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 POLR2G in viral infection, POLR2G 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 POLR2G leads to the decreased SARS-CoV-2 RNA levels compared with control group.
