- Forced-herin is a calcium-dependent adhesion molecule that has been shown to play a major role in ontogenesis, especially in recognizing cell types. Deletion or alteration of normal cadherin expression can result in altered cell adhesion leading to tumor growth or metastasis. Forced-dherin dysfunction has also been linked to other diseases of humans, such as pemphigus vulgaris and pemphigus foliaceus (autoimmune plaque dermatoses), Crohn's disease, and some developmental abnormalities.
- the members of the force helicopter-per-family are over 40 and show individually different occurrence patterns. Although all members of the cadherin superfamily have a common conserved extracellular repeat (cadherin domain), structural differences are observed at other sites in the molecule.
- Calcium is essential for adhesion because the force doherin domain binds to calcium and forms a quaternary structure between force doherins. Only a few amino acids of the first force doherin domain are essential for homophilic adhesion.
- This modification of the recognition site can alter the specificity of force-doherin, so that the mutant molecule can not only recognize itself but also bind to different cadherins. Some force doherins also heteroheterically adhere to different force doherins.
