Anchoring junctions: Hemidesmosomes
Like a half desmosome at the base of the cells
links to basal lamina
- A plaque anchors intermediate filaments inside the cell--ends are buried in plaque (contains desmoplakin-like protein).
-
- anchoring proteins called “integrins”, bind from the keratin molecules inside to laminins in the basal lamina. (Integrins are receptors for specific extracellular matrix proteins). Bind like “velcro”
