Introduction
Smallpox was an infectious disease unique to humans, caused by either of two virus variants, Variola major and Variola minor. The disease is also known by the Latin names Variola or Variola vera, which is a derivative of the Latin varius, meaning "spotted", or varus, meaning "pimple". The term "smallpox" was first used in Britain in the 15th century to distinguish variola from the "great pox" (syphilis). The last naturally occurring case of smallpox (Variola minor) was diagnosed on 26 October 1977.
Function
Essential serine/threonine-protein kinase that plays different role in the viral life cycle. Phosphorylates the host small ribosomal protein RACK1 thereby customizing the ribosomes to a state optimal for viral mRNAs (which contain poly-A leaders) but not for host mRNAs. Facilitates viral DNA replication by inhibiting host BANF1, a cellular host defense responsive to foreign DNA. Phosphorylates host BANF1 on serine and threonine residues; this leads to BANF1 relocalization to the cytoplasm, loss of dimerization and impaired DNA binding activity. Indeed, BANF1 activity depends on its DNA-binding property which is blocked by VPK1-mediated phosphorylation. Required for viral intermediate genes expression, probably by inhibiting host BANF1. Modulates cellular responses via host JUN by two different mechanisms, either by direct phosphorylation or by modulation of upstream JIP1-MAPK complexes. Seems to participate in the accumulation/processing of late proteins and thus in virion maturation.
