WebCadherins (calcium-dependent adherence proteins) also are associated with desmosomes and penetrate the cell membrane to interact with cognate proteins on adjacent cells. Cadherins function to hold the cells in contact with one another across desmosomes. Since cadherin binding is calcium dependent, these cell junctions are also calcium dependent. WebAlthough desmosomes are composed of structurally related sets of proteins, including cadherin and armadillo family members, a direct homologue of the key mechanosensor in AJs, α-catenin is lacking. Instead, desmosomes contain the cytoskeletal linker protein DSP with an important role in lateral clustering of cadherins and in linking KIFs to ...
