Integrin binds to?: (A) Fibronectin, (B) Vitronectin, (C) Collagen, (D) Laminin
Answer is D. Ans. (d) Laminin > FibronectinIntegrins localised in the plasma membrane are the major adhesion receptors connecting cells with components of the extracellular matrix. Integrins interact directly with laminin, fibronectin present in the basal lamina and intracellularly contact actin through intermediate proteins, such as alpha-actinin, vinculin,and talin.
