== Function ==
[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>
