Fig. 7. The extent of p368 phosphorylation is increased through the cell and is
maximal during S and G2/M. Synchronized cells collected at the
indicated cell-cycle stage were processed for immunoblotting and probed with
antibodies to p368 (
-p368), Cx43NT1 (
-Cx43), or vinculin (for a
loading control). The molecular weight or migration position of the Cx43 is
indicated on the right, and the ratio of the extent of p368 to Cx43NT1
antibody labeling is shown on the bottom line.
