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
The Cumberland Gap is a key passageway to lower and central Appalachia. The natural junction was a site well-known to Native Americans throughout the centuries. Upon physician and explorer Dr. Thomas Walker’s praise, the pass was expanded by a team of loggers led by none other than Daniel Boone.
Plasmodesmata Plasmodesmata (singular, plasmodesma) are small tubes that connect plant cells to each other, establishing living bridges between cells. Similar to the gap junction found in animal cells, the plasmodesmata penetrate both the primary and secondary cell walls, allowing certain molecules to pass directly from one cell to another.
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.
