They are known as “transmembrane receptors” meaning they receive messages for the cell and then transfer them to the inside of the cell, kind of like a bridge from one cell to to another and one cell to the ECM (Extracurricular Matrix). It's difficult to get a clear photo of an integrin but it's been thought to be a large structure. A discovery in 2001 proved integrin to resemble that of an inverted ‘V’. This is thought to be for the purpose of keeping the cell membrane closer to where the Logan's are bound.
Cadherin is an adhesive protein important for cells maintaining its structure. Cadherin can be found in vertebrates, invests, and nematodes. Cadherins have an intercellular into and an outer cellular unit. Within the cell the intercellular unto of the cadherin bonds to the inside of the cell. On the outside of one cell the outer cellular unit bind together with the outer cellular unit of cadherin of another cell. This holds the cells together creating a
