Introduction

When the first partial and complete sequences of Kaposi’s sarcoma herpesvirus were obtained (Neipel et al. 1997; Nicholas et al. 1997; Russo et al. 1996), it became apparent that the presence of multiple viral genes with low but significant homologies to mammalian proteins involved in signal transduction is one of the key features of this virus. While equivalents of some of these homologues had been found in other herpesviruses or other large DNA viruses, for example chemokines and chemokine receptors, others such as interleukin-6 had not previously been identified in a virus. Given the low sequence homology to their cellular counterparts and the fact that some of the cellular gene homologues occur in different large DNA viruses, it seems that such homologues have entered their respective viral genomes a long time ago in the early phases of DNA virus evolution. Their continued presence, however, points to a selective advantage during virus evolution, probably by...
