Degradation of connexins from the plasma membrane is regulated by inhibitors of protein synthesis.


Little is known about the mechanism and regulation of connexin turnover from the plasma membrane. We have used a combination of cell surface biotinylation, immunofluorescence microscopy, and scrape-load dye transfer assays to investigate the effect of the protein synthesis inhibitor cycloheximide on connexin43 and connexin32 after their transport to the… (More)
