Here's a little more about them:
* Structure: Gap junctions are formed by channels called connexons, which are made up of six protein subunits. These connexons from adjacent cells align to form a continuous channel between the two cells.
* Function: They allow for the passage of small molecules, ions, and even electrical signals between cells. This is important for a variety of processes, including:
* Cell communication: Gap junctions allow cells to communicate with each other quickly and efficiently.
* Coordination of cell activity: They help to synchronize the activities of cells in tissues and organs.
* Development and growth: They play a role in the development and growth of tissues and organs.
* Location: Gap junctions are found in a variety of tissues, including heart muscle, smooth muscle, and epithelial tissue.
