Functioni

Capsid protein VP2 self assembles to form an icosahedral capsid with a T=13 symmetry, about 70 nm in diameter, and consisting of 260 VP2 trimers. The capsid encapsulates the genomic dsRNA. VP2 is also involved in attachment and entry into the host cell By similarity.
The precursor of VP2 plays an important role in capsid assembly. First, pre-VP2 and VP2 oligomers assemble to form a procapsid. Then, the pre-VP2 intermediates may be processed into VP2 proteins by proteolytic cleavage mediated by VP4 to obtain the mature virion. The final capsid is composed of pentamers and hexamers but VP2 has a natural tendency to assemble into all-pentameric structures. Therefore pre-VP2 may be required to allow formation of the hexameric structures By similarity.
Protease VP4 is a serine protease that cleaves the polyprotein into its final products. Pre-VP2 is first partially cleaved, and may be completely processed by VP4 upon capsid maturation By similarity.
Capsid protein VP3 plays a key role in virion assembly by providing a scaffold for the capsid made of VP2. May self-assemble to form a T=4-like icosahedral inner-capsid composed of at least 180 trimers. Plays a role in genomic RNA packaging by recruiting VP1 into the capsid and interacting with the dsRNA genome segments to form a ribonucleoprotein complex. Additionally, the interaction of the VP3 C-terminal tail with VP1 removes the inherent structural blockade of the polymerase active site. Thus, VP3 can also function as a transcriptional activator By similarity.
Structural peptide 1 is a small peptide derived from pre-VP2 C-terminus. It destabilizes and perforates cell membranes, suggesting a role during entry By similarity.
Structural peptide 2 is a small peptide derived from pVP2 C-terminus. It is not essential for the virus viability, but viral growth is affected when missing By similarity.
Structural peptide 3 is a small peptide derived from pVP2 C-terminus. It is not essential for the virus viability, but viral growth is affected when missing By similarity.

Post-translational modificationi

Specific enzymatic cleavages yield mature proteins. The capsid assembly seems to be regulated by polyprotein processing. The protease VP4 cleaves itself off the polyprotein, thus releasing pre-VP2 and VP3 within the infected cell. During capsid assembly, the C-terminus of pre-VP2 is further processed by VP4, giving rise to VP2, the external capsid protein and three small peptides that all stay closely associated with the capsid By similarity.

Interactioni

Subunit structurei

Capsid protein VP2 is a homotrimer. A central divalent metal stabilizes the VP2 trimer, possibly cobalt By similarity. Capsid protein VP3 is a homodimer. Capsid protein VP3 interacts (via C-terminus) with VP1 in the cytoplasm Capsid VP3 interacts with VP2 By similarity.
