In this work, we show that the proteins Pkc1 and Pfy1 play a role in the repolarization of the actin cytoskeleton and in cell survival in response to oxidative stress. We have also developed an assay to determine the actin polymerization capacity of total protein extracts using fluorescence recovery after photobleaching techniques and actin purified from rabbit muscle. This assay allowed us to demonstrate that Pfy1 promotes actin polymerization under conditions of oxidative stress, while Pkc1… CONTINUE READING
