dNTP depletion and beyond: the multifaceted nature of SAMHD1-mediated viral restriction.
SAMHD1 is a dNTPase of mammalian cells. In 2011, SAMHD1 was found to be a host restriction factor against retroviruses through dNTP reduction. Recent research provides evidence that the antiviral mechanisms of SAMHD1 cannot be explained solely by its dNTPase activity. Instead, the versatility of SAMHD1-mediated restriction of various viruses suggests that its antiviral mechanisms extend beyond dNTP depletion. This explains the multifaceted and broad restriction functions of SAMHD1 that play a significant role in innate antiviral immunity.
期刊介绍:
Journal of Virology (JVI) explores the nature of the viruses of animals, archaea, bacteria, fungi, plants, and protozoa. We welcome papers on virion structure and assembly, viral genome replication and regulation of gene expression, genetic diversity and evolution, virus-cell interactions, cellular responses to infection, transformation and oncogenesis, gene delivery, viral pathogenesis and immunity, and vaccines and antiviral agents.
