    UBL7 Enhances Antiviral Innate Immunity by Promoting Lys27-Linked Polyubiquitination of MAVS

    Ubiquitin-like protein BMSC-UbP (UBL7)-deficient mice exhibited increased susceptibility to viral infection due to attenuated antiviral innate immunity. UBL7 enhanced innate immune response to viral infection by promoting the K27-linked polyubiquitination of mitochondrial antiviral signaling protein (MAVS).
