Desmosomes and cadherin
Webcytoskeleton. Desmosomes are adhesion proteins that contain a series of proteins, particularly desmogleins and desmo-collins—glycoproteins of the cadherin supergene family which link to cytokeratins via desmoplakins and plakoglobin (Buxton and Magee, 1992). Cadherins are composed of an extracellular WebDesmosomes. Like AJs, desmosomes are cadherin-based, multiprotein complexes that couple intercellular adhesion not to the actin cytoskeleton, but instead, to the IF system (Fig. 2 B). Desmosomes are mainly found in epithelia and in the heart of vertebrates. The desmosomal cadherin subfamily consists of desmogleins (in humans, Dsg1–4) and ...
