Brg1 is phosphorylated in vitro by CK2. A, schematic representation of the location of the putative sites for CK2 phosphorylation identified by NetphosK ( 9 , 20 ). B, representative autoradiograms of in vitro CK2-treated WT-, SA-, and SE-Brg1 ( top ). A representative Western blot detecting Brg1 is shown for comparison ( bottom ). EV, empty vector. C, Brg1 labeling was quantified by normalizing autoradiography signals to the Western blotting for Brg1. Data represent the average of three independent experiments ± S.D.; *, p
