Characterization of a conserved gene block in the murine cytomegalovirus genome.
The nucleotide sequence between the lytic origin and the gH gene of the murine cytomegalovirus genome (map units 0.416-0.455) was determined. Five of the 15 open reading frames identified encode polypeptides, which exhibit significant homology to polypeptides of human cytomegalovirus (HCMV) (UL69, UL71, and UL73) and to polypeptides of several other herpesviruses (dUTPase and helicase/primase). The location in the genome of the five open reading frames and their direction of transcription is perfectly conserved between murine cytomegalovirus (MCMV) and HCMV. These data suggest that MCMV and HCMV have a highly related genome organization. Thus, MCMV offers a good model for molecular and functional analysis of cytomegalovirus genes in vitro and in vivo.
