Abstract

Inhibitor of DNA-binding 1 (ID1) protein has been studied intensively for its functions in tumorigenesis and maintenance of stem cell-like properties, but its roles in virus Infection are less understood. In the present study, we have clearly shown that the foot-and-mouth disease virus (FMDV) promotes ID1 degradation via Cdh1-mediated ubiquitination to facilitate its replication. Mechanistic investigations reveal Forkhead Box O1 (FOXO1) as an ID1 partner, which suppresses interferon regulatory factors 3 expression and interferon (IFN) production. Further investigation identified that ID1 suppresses FOXO1 transcription activity through HDAC4-mediated deacetylation, promoting IFN production and Antiviral immune response. These studies establish a prominent role for ID1 in suppressing FDMV replication, which may be extended to other viruses.
