Which transmembrane adhesion proteins found in hemidesmosomes specifically bind to the basal lamina glycoprotein laminin?

Explanation

Integrin α6β4 is the key transmembrane adhesive molecule in hemidesmosomes that interacts directly with laminin in the basal lamina, facilitating stable cell-matrix adhesion. Other options such as catenins, desmoplakin, cadherins, and desmoglein are involved in different types of cell junctions but do not bind laminin in hemidesmosomes.
