Function
CAPSD_HEVUS Plays a role in the inhibition of host antibody-mediated neutralization without blocking viral cell entry.[1] 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 (By similarity). Binds to heparin surface proteoglycans (HSPGs) to mediate viral entry. 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:P29326][UniProtKB:P33426][UniProtKB:Q81871]
