GORASP1 and cytomegalovirus infection: As observed in HF cells, HCMV infection of the HF cell line expressing Grasp65wt-GFP led to the accumulation of a more slowly migrating form of Grasp65-GFP in lysates that were not treated with CIP, whereas phosphatase treatment of the infected-cell lysates with CIP increased the mobility of Grasp65wt-GFP, indicating that the protein was posttranslationally modified by phosphorylation (Fig. 7).
