HSV Replication
HSV-1 DNA Replication
Category: Virology
from Stacey A. Leisenfelder and Sandra K. Weller writing in Alphaherpesviruses: Molecular Virology:
The cis- and trans-acting elements required for DNA synthesis of Herpes Simplex Virus (HSV) have been identified, and genetic and biochemical analyses have provided important insights into how they work together to replicate the large double-stranded viral genome. Furthermore, viral enzymes involved in DNA replication have provided a rich store of useful targets for antiviral therapy against herpesviruses. Despite these advances, many questions remain unresolved concerning the overall mechanism of genome replication. For instance, it has long been recognized that the products of viral DNA replication are head-to-tail concatemers; however, it is not clear how these concatemers are generated. A recent review summarizes the known functions of viral replication proteins and explore the possibility that these viral proteins may function in combination with cellular proteins to produce concatemers suitable for packaging into preformed viral capsids.
