KRT17 and infection: To test the involvement of mTOR kinase and casein kinases 1 and 2 in ARP101-induced phosphorylation of Ser349 or Ser403 during infection, we used a combination of Torin-1 (selective inhibitor of mTORC1 and mTORC2), TBCA (tetrabromocinnamic acid; selective inhibitor of casein kinase 2), CK1-7 (selective inhibitor of casein kinase 1), and ARP101 in HCMV-infected cells.
