Following the treatment of cytomegalovirus (CMV, strain Colburn)-infected cells with the drug cycloheximide early after infection, dramatically enhanced amounts of an otherwise minor protein are synthesized. Size and charge estimates, based on one- and two-dimensional separations in denaturing polyacrylamide gels, indicate that this protein has a molecular weight of 94K and an acidic net charge. Results of experiments to investigate its synthesis indicate that (i) the 94K protein is expressed by 2-4 hr after infection, (ii) its appearance requires de novo RNA synthesis, (iii) both the protein and its mRNA appear to be metabolically stable, and (iv) the increased amount of this protein following cycloheximide inhibition appears to be the result of selective mRNA amplification. On the basis of its partitioning during detergent fractionation procedures, it is suggested that the 94K protein may function in the cytoplasm.
