摘要:
Cell-to-cell channels are often seen clustered at cell-cell contacts into the so-called gap junction plaques. The mechanism of this clustering is unknown. We show that the clustering of cell-to-cell channels composed of connexin43 is induced by elevation of cyclic AMP. The cAMP-induced clustering is enhanced by inhibition of glycosylation and abolished by disruption of microfilaments. Channel clustering thus seems to be regulated by cAMP and glycosylation and to involve microfilaments.
