Describe the structure and function of desmosomes
What will be an ideal response?
Desmosomes act like "spot rivets" that anchor together two adjacent but non-touching cells. A desmosomes consists of two components: (1) a pair of dense, button-like cytoplasmic thickenings known as plaques located on the inner surface of each of the two adjacent cells, and (2) strong filaments containing cadherins that extend across the space between the two cells and attach to the plaque on both sides. These intercellular filaments bind adjacent plasma membranes together so that they resist being pulled apart. Thus, desmosomes are adhering junctions. They are the strongest cell-to-cell connections.
