From: HCMV pUS28 initiates pro-migratory signaling via activation of Pyk2 kinase
Pyk2-F402Y Blocks pUS28 Signaling to RhoA. FAK-/- fibroblasts were infected with Ad-Trans and Ad-pUS28 +/- Pyk2-WT or -F402Y for 18 hrs. Cells were stimulated with 40 ng/ml CCL5 for the indicated times. Lysates were immunoprecipitated with Rhotekin-RBD-GST Agarose and analyzed by western blot for RhoA. Input lysates were analyzed for total RhoA and to confirm adenovirus infection efficiency. The percent active RhoA was quantified via ImageJ densitometry of both IP and total lysate western blots.
