Figure 7. Inhibiting Cx45CT dimerization alters phosphorylation and protein partner interactions.
MDCK cells stably expressing Cx45 WT or 6E were cultured, lysed, and immunoprecipitated to assess total phosphorylation levels and interactions with β-tubulin, Drebrin, and Nedd4. A) Representative Western blots of immunoprecipitated Cx45 WT or 6E blotting with a general anti-pY antibody. (n=3, ** P<0.01) Representative Western blot of B) β-tubulin (n=7, ***P<0.001), C) Drebrin (n=3, **P<0.01), and D) Nedd4 (n=3, **P<0.01) co-immunoprecipitated with either Cx45 WT or 6E. Data presented as mean fold change + s.e.m. relative to the first WT replicate. Statistics are two-tailed unpaired Student’s T-test.
