The small nonstructural protein NS2 of the minute virus of mice (MVM) is required for efficient viral replication, although its mode of action is unclear. Here we demonstrate that NS2 and survival motor neuron protein (Smn) interact in vitro and in vivo. NS2 and Smn also colocalize in infected nuclei at late times following MVM infection.

The non-structural proteins NS1 and NS2 of the parvovirus minute virus of mice (MVM) are required for efficient virus replication. It has previously been shown that NS1 and NS2 interact and colocalize with the survival motor neuron (Smn) gene product in novel nuclear structures that are formed late in infection, termed Smn-associated APAR (autonomous parvovirus-associated replication) bodies (SAABs). It is not clear what molecular viral intermediate(s) contribute to SAAB formation. The current results address the role of NS2 in SAAB formation. In highly synchronized wild-type MVM infection of murine A9(2L) cells, NS2 colocalizes with Smn and other SAAB constituents. An MVM mutant that does not produce NS2 still generates SAABS, albeit with a temporal delay. The lag in SAAB formation seen in the absence of NS2 is probably related to the temporal delay in virus replication, suggesting that, whilst NS2 is required for efficient viral infection, it is dispensable for SAAB formation.
