Human herpesvirus (HHV) proteins with human homologs. Alternative names for the HHVs are HHV-1, human simplex virus 1; HHV-2, human simplex virus 2; HHV-3, varicella zoster virus; HHV-4, Epstein-Barr virus; HHV-5, human cytomegalovirus; and HHV-8, Kaposi's sarcoma–associated herpesvirus. Labels show the virus protein function, the name of a member of the HPF (homologous proteinfamily) or singleton, and, for HPFs, the corresponding number in brackets. All the annotations and HPF numbers are taken from VIDA. Note that in some cases more than one HPF/singleton, shown as separate rows in Table 1, are shown together here. This corresponds to highly divergent families. The graph is color coded according to functional class: light green, DNA replication; dark blue, nucleotide repair/metabolism; light blue, enzyme; purple, gene expression regulation; yellow, glycoprotein; red, host-virus interaction; and black, unknown. Diagonal lines within a box indicate two gene copies (per viral genome); vertical lines, three copies; and horizontal lines, 10 copies.
