Protein phosphorylation and hydrogen ions modulate calcium-induced closure of gap junction channels.
R O Arellano et al.
Biophysical journal, 57(2), 363-367 (1990-02-01)
The regulation of the cell-to-cell pathway formed by gap junctions seems to involve the interaction of the junctional channels with either calcium or hydrogen ions, as well as protein phosphorylation and calmodulin. These mechanisms of junctional regulation have been considered
