RESUMO

The US3 genes of herpes simplex virus serotypes 1 and 2, and the corresponding gene of varicella-zoster virus, encode proteins whose sequences are clearly homologous to members of the protein kinase family of eukaryotes and retroviruses. Similarity is most characteristic, and strongest, in an 80 residue region comprising part of the catalytic structure of the kinases. In this region the herpesvirus proteins are most like a yeast cell division control protein, and least like the retrovirus protein-tyrosine kinases. We consider that the herpesvirus proteins are probably involved in modulation of cellular processes during lytic infection, although other roles are also possible, for example in latent infection.
