Cx43-mApple and Cx40.8-EGFP co-assemble in common gap junction channels.
High resolution fluorescence microscopy was used to provide evidence for co-association of Cx43-mApple and Cx40.8-EGFP in common gap junction channels. Constructs that were co-transfected in HeLa cells are indicated to the left of the panels (A, B) Homo sapiens (Hs) Cx43-mApple + Hs Cx43-EGFP show uniformly yellow plaques, suggesting co-asociation. (C, D) Hs Cx43-mApple + Hs Cx26-EGFP show discrete green and red domains, revealing a lack of co-association. Arrows indicate green Hs Cx26-EGFP localization and arrowheads indicate red Hs Cx43-mApple localization. (E, F) Danio rerio (Dr) Cx43-mApple + Dr Cx40.8-EGFP show uniform yellow distribution.
