Homophilic binding

Homophilic binding is a common name for process that is involved in cell adhesion, also called cell-junction. Homophilic binding is a binding between two identical components of the cell junction. In the cell we have cadherins that are Ca2+ dependent like:
 * tight junction
 * adherence junction
 * desmosome junction

The Homophilic binding is different from heterophilic binding in that the latter is a binding between 2 non-identical components of each cell, like Selectin or integrins.
