The transmembrane adhesive molecules present in hemi desmosomes which specifically binds to basal lamina glycoprotein laminin are______________?
Correct answer: A. Integrin a6-B4
- A. Integrin a6-B4
- B. The catenins desmoplakin
- C. cadherins desmoglein
- D. a and B catenin
Explanation
Hemidesmosomes use integrin α6β4 to attach epithelial cells to laminin in the basal lamina. Cadherins, catenins and desmoplakin are associated mainly with cell-cell junctions rather than this cell-matrix attachment.
