== Function == | |||
[https://www.uniprot.org/uniprot/CAPSD_HEVBU CAPSD_HEVBU] Plays a role in the inhibition of host antibody-mediated neutralization without blocking viral cell entry.[UniProtKB:Q9YLQ9] Forms an icosahedral capsid with a T=1 symmetry and a 34 nm diameter. The capsid is composed of 60 copies linked to each other. Binds to the 5' end of the genomic RNA to mediate genome encapsidation (PubMed:14671114, PubMed:15557331). Binds to heparin surface proteoglycans (HSPGs) to mediate viral entry (By similarity). Additionally, the interactions with host ASGR1 and ASGR2 facilitate viral infection of hepatocytes (By similarity). Inhibits IFN production by blocking host TBK1-induced IRF3 phosphorylation (By similarity). The nuclear form probably modulates host gene expression (By similarity).[UniProtKB:P33426][UniProtKB:Q81871]<ref>PMID:14671114</ref> <ref>PMID:15557331</ref> [https://www.uniprot.org/uniprot/ORF3_HEVBU ORF3_HEVBU] May act as a viral regulatory protein involved in the modulation of mitogenic signaling pathways. May be involved in virion morphogenesis and viral pathogenesis. Expedites the processing and secretion of AMBP from the hepatocyte (By similarity). | |||
