[[https://www.uniprot.org/uniprot/NS1_MUMIP NS1_MUMIP]] Multifunctional protein that plays an essential role in viral DNA replication. Inhibits the host cell cycle during the G1/S transition, the S-phase, and the G2/M transition. These arrests may provide essential cellular factors for viral DNA replication. Interacts specifically with the viral DNA origin of replication and plays a direct role in DNA replication. Participates in the transcriptional regulation of several promoters including the viral p38 promoter that regulates the expression of VP1 and VP2 transcripts. Promotes apoptosis in host cell.<ref>PMID:11602746</ref> <ref>PMID:21295324</ref> <ref>PMID:7636987</ref> <ref>PMID:9188601</ref>

Members of the Parvoviridae family all encode a non-structural protein 1 (NS1) that directs replication of single-stranded viral DNA, packages viral DNA into capsid, and serves as a potent transcriptional activator. Here we report the X-ray structure of the minute virus of mice (MVM) NS1 N-terminal domain at 1.45A resolution, showing that sites for dsDNA binding, ssDNA binding and cleavage, nuclear localization, and other functions are integrated on a canonical fold of the histidine-hydrophobic-histidine superfamily of nucleases, including elements specific for this Protoparvovirus but distinct from its Bocaparvovirus or Dependoparvovirus orthologs. High resolution structural analysis reveals a nickase active site with an architecture that allows highly versatile metal ligand binding. The structures support a unified mechanism of replication origin recognition for homotelomeric and heterotelomeric parvoviruses, mediated by a basic-residue-rich hairpin and an adjacent helix in the initiator proteins and by tandem tetranucleotide motifs in the replication origins.
