All of the following statements about cadherins are true, EXCEPT:

A
Adhesion is Ca++-dependent and homophilic
B
When mixed together, cells expressing different cadherins so out into homotypic cell aggregates
C
Cadherins associate with the actin cytoskeleton
D
Cadherins interact with components of the basement membrane
High-Yield Explanation
This is an incorrect statement and hence the correct answer for this EXCEPT question. Cadherins are involved in cell-cell adhesive interactions and not cell-ECM interactions. Binding of epithelial cells to basement membrane components, such as occurs with hemidesmosomes, involves integrins.
