Question:
Gap junctions are dynamic structures that, like conventional ion channels, are gated: they can close by a reversible conformational change in response to changes in the cell. The permeability of gap junctions decreases within seconds, for example, when the intracellular Ca2+ concentration is raised. Speculate why this form of regulation by Ca2+ might be important for the health of a tissue.
