==Porcine Parvovirus Capsid==
-
The structure of baculovirus-expressed porcine parvovirus (PPV) capsids, was solved using X-ray crystallography and was found to be similar to the, related canine parvovirus (CPV) and minute virus of mice (MVM). The PPV, capsid protein has 57 % and 49 % amino acid sequence identity with CPV and, MVM, respectively, but the degree of conservation of surface-exposed, residues is lower than average. Consequently, most of the structural, differences are on the surface and are the probable cause of the known, variability in antigenicity and host range. The NADL-2 and Kresse strains, of PPV have distinct tissue tropisms and pathogenicity, which are mediated, by one or more of the amino acid residues 381, 386, and 436. These, residues are on or near the surface of the virus capsid, where they are, likely to be associated with virus-cell interactions.

== Function ==
 +
[https://www.uniprot.org/uniprot/CAPSD_PAVPN CAPSD_PAVPN] Capsid protein self-assembles to form an icosahedral capsid with a T=1 symmetry, about 22 nm in diameter, and consisting of 60 copies of two size variants of the capsid proteins, VP1 and VP2, which differ by the presence of an N-terminal extension in the minor protein VP1. The capsid encapsulates the genomic ssDNA. Capsid proteins are responsible for the attachment to host cell receptors. This attachment induces virion internalization predominantly through clathrin-dependent endocytosis. Binding to the host receptors also induces capsid rearrangements leading to surface exposure of VP1 N-terminus, specifically its phospholipase A2-like region and putative nuclear localization signal(s). VP1 N-terminus might serve as a lipolytic enzyme to breach the endosomal membrane during entry into host cell and might contribute to virus transport to the nucleus (By similarity).
