Mapping of the Major Glycoprotein Gene of Human Cytomegalovirus

The gene coding for the most abundant glycoprotein (gp58) of human cytomegalovirus (HCMV), strain AD169, was physically mapped on the viral genome. A monospecific rabbit antiserum against gp58 was used to screen a cDNA library that was constructed from poly(A)+ RNA of HCMV-infected cells in the prokaryotic expression vector λ gt11. A cDNA clone was identified which synthesized part of the glycoprotein. It allowed localization of the coding region within the right terminal sequence of the HindIII-F fragment between map coordinates 0·344 and 0·380 of HCMV virion DNA.
