Stable Cx43 expression in infected Cx43−/− cells and phosphorylation of Cx43. Stable Cx43 expression in infected Cx43−/− cells and phosphorylation of Cx43. A. Immunoprecipitation was performed using affinity-purified rabbit anti-Cx43 antibody and proteins were resolved on a 12% SDS-polyacrylamide gel. Western blot was performed using rabbit polyclonal anti-Cx43 antibody. Cx43−/− pMSCV mock-infected cells (lane 1), Cx43−/− pMSCV Cx43 wild type (lane 2), and Cx43−/− pMSCV F199L Cx43 (lane 3). NP, non-phosphorylated form of Cx43; P1 and P2, slower migrating phosphorylated forms of Cx43. B. HeLa cells transiently transfected with Cx43 were metabolically labeled for 4 h. Anti-Cx43 immunoprecipitates were resolved on a 7.5 % polyacrylamide gel. Mock transfected (lane 1), Cx43 wild type (lane 2), and Cx43 F199L (lane 3). P0, P1, and P2, phosphorylated forms of Cx43.
