Previous GeneCards Identifiers for HERC5 Gene
This gene is a member of the HERC family of ubiquitin ligases and encodes a protein with a HECT domain and five RCC1 repeats. Pro-inflammatory cytokines upregulate expression of this gene in endothelial cells. The protein localizes to the cytoplasm and perinuclear region and functions as an interferon-induced E3 protein ligase that mediates ISGylation of protein targets. The gene lies in a cluster of HERC family genes on chromosome 4. [provided by RefSeq, Jul 2008]
GeneCards Summary for HERC5 Gene
HERC5 (HECT And RLD Domain Containing E3 Ubiquitin Protein Ligase 5) is a Protein Coding gene. Diseases associated with HERC5 include Influenza. Among its related pathways are RIG-I/MDA5 mediated induction of IFN-alpha/beta pathways and Regulation of Glucokinase by Glucokinase Regulatory Protein. GO annotations related to this gene include poly(A) RNA binding and ubiquitin-protein transferase activity. An important paralog of this gene is HERC6.
UniProtKB/Swiss-Prot for HERC5 Gene
Major E3 ligase for ISG15 conjugation. Acts as a positive regulator of innate antiviral response in cells induced by interferon. Functions as part of the ISGylation machinery that recognizes target proteins in a broad and relatively non-specific manner. Catalyzes ISGylation of IRF3 which results in sustained activation, it attenuates IRF3-PIN1 interaction, which antagonizes IRF3 ubiquitination and degradation, and boosts the antiviral response. Catalyzes ISGylation of influenza A viral NS1 which attenuates virulence; ISGylated NS1 fails to form homodimers and thus to interact with its RNA targets. Catalyzes ISGylation of papillomavirus type 16 L1 protein which results in dominant-negative effect on virus infectivity. Physically associated with polyribosomes, broadly modifies newly synthesized proteins in a cotranslational manner. In an interferon-stimulated cell, newly translated viral proteins are primary targets of ISG15.
