"Monomer. Homodimer. Exists in equilibrium between monomers and dimers in solution. Interacts with the histone-like nucleoprotein; this interactions bridge the virus core to the capsid. Interacts with core protein X; this interactions bridge the virus core to the capsid. Interacts with the endosome lysis protein VI; this interactions bridge the virus core to the capsid. Interacts with the peripentonal hexons. Interacts with host NPM1; this interaction might play a role in virus assembly."xsd:string
