Selective permeability means that the cell membrane has some control over what can cross it, so that only certain molecules either enter or leave the cell. Molecules can cross the plasma membrane in three main ways.

Sometimes diffusing particles encounter regions in which the permeability is reduced, ... Membranes, through their selective alteration of the otherwise inexorable process of diffusion, cause a number of interesting cellular phenomena. When water can cross the membrane and dissolved particles cannot, osmosis occurs.

Clearly, much needs to be done to fully catalogue the selective permeability characteristics imparted to gap junction channels by their connexin composition. We have only just begun the comparison of different connexins and the cataloguing of natural permeants, and no clear theme has yet emerged.
