Anchoring junctions : Desmosomes
Like a spot weld or button.
- Formed by a dense intracellular plaque on each side into which keratin filaments are looped. (desmoplakins; plakoglobin; 75 kD polypeptide; desmoglein)
- Cadherin molecules (“calcium dependent adhesion molecules”) extend across the extracellular space to bind the cells together. (Desmocollins-I, II & desmogleins)
