Cellular DUBs have an important role in many signaling pathways, including immune signaling, apoptosis, oncogenesis and developmental pathways.12, 13, 14 Likewise, our findings as well reveal that upon infection, HCMV-DUB inhibits synthesis of I-IFNs, an anti-cancer factor, by deubiquitinating several signaling molecules such as TNF receptor-associated factor (TRAF)-6 and -3, interleukin-1 receptor-associated kinase-1 (IRAK1), interferon regulatory factor (IRF)-7 or stimulator of interferon genes (STING) that have a key role in anti-viral innate immunity. Here, STING1 is linked to cancer.
