These results suggest that (1) DNAJB6 may specifically interact with UL70, (2) that the tag sequence does not affect the interaction and co-localization of UL70 with DNAJB6, and (3) that the results obtained in experiments with the tagged UL70 protein may truly reflect those results obtained with the native untagged protein during HCMV infection. This evidence concerns the gene DNAJB6 and cytomegalovirus infection.
