From: HCMV pUS28 initiates pro-migratory signaling via activation of Pyk2 kinase
Pyk2-Associated Proteins are Cell-Type and Signal-Specific. SMC or U373 were infected with Ad-Trans and Ad-Pyk2 +/- Ad-pUS28 and stimulated with 20% serum or 40 ng/ml CCL5 for 0, 5, 10, 15, 30 or 60 min. Pyk2 was immunoprecipitated using myc antibodies. Pyk2 complexes were analyzed via tandem mass spectrometry. Results shown are proteins identified with >3 spectral hits for all peptides. (A) Total hits for Pyk2-associated proteins in RSMC and U373. (B) Proteins for which Pyk2-association was induced over the timecourse of stimulation in RSMC and U373. For data analysis, a protein was considered induced if the average spectral hits for all peptides for timepoints 5, 10, 15, 30 and 60 min was greater than twice the spectral hits for all peptides in unstimulated cells.
