Phylogenetic Analysis of Homologous Proteins Encoded by UL2 and UL23 genes of Herpesviridae / 中国病毒学

The proteins encoded by the Herpesviridae β-gene play a critical role in the replication stage of the virus. In this paper, phylogenetic analyses provided evidence that someβ-gene products, such as UL2 and UL23 from HSV1, have their homologous genes in its family, and also exist in prokaryotic organisms, indicating that these viruses appear to have been assembled over evolutionary time by numerous independent events of horizontal gene transfer.
