Signaling in Gap Junction The function of Gap Junctions in cell and tissue biology is of utmost importance as Gap-Junctional Intercellular Communication exists in nearly every mammalian cell types. http://www.sabiosciences.com/pathway.php?sn=Signaling_in_Gap_Junction
passief iontransport door kanaaltjes Gap Junctions are channels between cell membranes that allow ions and small molecules to pass directly from one cell to another. These channels are formed by membrane proteins called connexins. Six connexins in the cell membrane form a channel called a connexon. Connexons from two cells form a gap junction. Gap junctions permit electrical signals to pass directly from one cell to another.
