Practice question
Question
Integrin molecules link ECM to actin cytoskeleton. Integrins bind to which ECM macromolecule? (June 2012)
Explanation
Fibronectin, is consistent with established principles of cell signaling, receptor pharmacology and cellular regulation. Experimental measurements of binding parameters, genetic loss-of-function studies and pharmacological interventions all converge on the same interpretation. Related options address neighboring concepts but do not satisfy the precise criterion stated in the question.
