HERC5 (E3 ISG15 - protein ligase HERC5) is a major E3 ligase for ISG15 conjugation. It acts a positive regulator of innate antiviral response in cells induced by interferon. HERC5 functions as a part of the ISGylation machinery that recognizes target protein in a broad and relatively non-specific manner. It catalyzes ISGylation of IRF3 - which results in sustained activation, it attenuates IRF3-PIN1 interaction - which antagonizes IFR3 ubiquitination and degradation, and boosts the antiviral repsonse. HERC5 is physically assocated with polyribosomes and broadly modifies newly synthesized proteins in a cotranslational manner.
