rotaviruses share some features of replication with reoviruses , yet antigenic and molecular properties of the outer capsid proteins , vp4 ( a protein whose cleavage is required for infectivity , possibly by mediating fusion with the cell membrane ) and vp7 ( a glycoprotein ) , show more similarities with those of other viruses such as the orthomyxoviruses , paramyxoviruses , and alphaviruses .
