  Function in Host
DNA-dependent RNA polymerase catalyzes the transcription ofmitochondrial DNA into RNA using the four ribonucleoside triphosphatesas substrates. Component of the mitochondrialtranscription initiation complex, composed at least of TFB2M, TFAM andPOLRMT that is required for basal transcription of mitochondrial DNA. In this complex, TFAM recruits POLRMT to a specificpromoter whereas TFB2M induces structural changes in POLRMT to enablepromoter opening and trapping of the DNA non-template strand. [1-2]

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