Following entry into the host cell, low intracellular or intravesicular Ca(2+) concentration probably causes the calcium-stabilized VP7 trimers to dissociate from the virion. This step is probably necessary for the merane-disrupting entry step and the release of VP4, which is locked onto the virion by VP7.
