...Rachael P. Norris; Mark Terasaki ABSTRACT Gap junctions have well-established roles in cell–cell communication by way of forming permeable intercellular channels. Less is understood about their internalization, which forms double membrane vesicles containing cytosol and membranes from another cell...

...Rachael M. Kells-Andrews; Rachel A. Margraf; Charles G. Fisher; Matthias M. Falk ABSTRACT Gap junctions (GJs) assembled from connexin (Cx) proteins allow direct cell–cell communication. While phosphorylation is known to regulate multiple GJ functions, much less is known about the role of ubiquitin...

..., yet the C-terminal domain of Cx43 regulated the proportion of gap-junction-like clusters that acquired a low Cx43 mobility state. Collectively, these studies show that Cx43 establishes residency at all cell-surface membrane domains, and progressively acquires assembly states that probably reflect...

.... Here, we took advantage of naturally occurring loss-of-gap-junction function mutations of Cx50 (ortholog of chick Cx45.6) and generated the corresponding site mutants in Cx45.6: Cx45.6(D47A) and Cx45.6(P88S). In contrast to wild-type Cx45.6, the mutants failed to form functional gap junctions...
