HERC5: Proteins and Enzymes

The HERC5 gene encodes for a 1,024 amino acid long, 116kDA E3 1SG15-protein ligase HERC5 protein near a cluster of HERC family genes located on chromosome 4. The protein coded for by the HERC5 gene localizes to the cytoplasm and perinuclear region and works as an interferon-induced E3 protein ligase. In doing so, it controlls ISGylation of protein targets. The HERC5 gene has been researched regarding influenza, malaria, teratoma, angelman syndrom, and carcinoma. The HERC5 gene interacts in interferon signaling, cytokine signaling in the immune system, and negative regulation of RIG-I/MDA4 signaling with interactions in NME2, CCNA2, ERCC2, PITX2, and NME1-NME2 genes.
