Autonomous parvovirus minute virus of mice (MVM) DNA replication is
strictly dependent on cellular factors expressed during the S phase of
the cell cycle. Here we report that MVM DNA replication proceeds in
specific nuclear structures termed autonomous parvovirus-associated replication bodies, where components of the basic cellular replication machinery accumulate. The presence of DNA polymerases

In Vivo Accumulation of Cyclin A and Cellular
Replication Factors in Autonomous Parvovirus Minute Virus of
Mice-Associated Replication Bodies
and
in
these bodies suggests that MVM utilizes partially preformed cellular
replication complexes for its replication. The recruitment of cyclin A
points to a role for this cell cycle factor in MVM DNA replication
beyond its involvement in activating the conversion of virion
single-stranded DNA to the duplex replicative form.
