WebShort proteins called cadherins in the plasma membrane connect to intermediate filaments to create desmosomes. The cadherins join two adjacent cells together and maintain the cells in a sheet-like formation in organs and tissues that stretch, like the skin, heart, and muscles. A desmosome forms a very strong spot weld between cells. WebAs desmosomes and AJs control Rho and actin dynamics, this potentially provides additional pathways to allow these junctions to integrate the regulation of cell shape and balanced renewal versus differentiation in the epidermis. Rho-family dependent modulation of the actin cytoskeleton can regulate cell behaviors through transcription.
