== Function == | |||
[https://www.uniprot.org/uniprot/CAPSD_HASV1 CAPSD_HASV1] The capsid polyprotein VP90 self-assembles and undergoes a proteolytic cleavage by host caspases to yield the immature VP70 virion.[UniProtKB:Q9IFX1] The immature virion is composed of 180 VP70 subunits with 90 dimeric spikes and displays a T=3 icosahedral symmetry (By similarity). During maturation, VP70 undergoes a loss of 60 peripentonal spikes, which likely plays an important role in viral infectivity (By similarity).[UniProtKB:Q9IFX1] Self-assembles to form an icosahedral capsid with a T=3 symmetry, about 43 nm in diameter (PubMed:26656707). This forms contains only 30 spikes located on the icosahedral 2-fold axes (PubMed:26656707).<ref>PMID:26656707</ref> VP25 and VP27 Forms the spikes at the surface of the virion (PubMed:26656707). This forms contains only 30 spikes located on the icosahedral 2-fold axes (PubMed:26656707). Plays a role in the attachment to target host cell (Probable). This attachment induces virion internalization through clathrin-dependent endocytosis (By similarity).[UniProtKB:Q9IFX1]<ref>PMID:26656707</ref> VP25 and VP27 Forms the spikes at the surface of the virion (PubMed:26656707). This forms contains only 30 spikes located on the icosahedral 2-fold axes (PubMed:26656707). Plays a role in the attachment to target host cell (PubMed:33396308).
