Which glycoprotein, present in large amounts within the basement membrane, contains binding sites for both extracellular matrix components and cell surface receptors?

Explanation

Laminin is a major glycoprotein of the basement membrane that has domains allowing it to bind both extracellular matrix molecules and cell surface receptors, facilitating cell adhesion and signaling. Fibronectin, E-Cadherin, and Tenascin have different roles and locations in the extracellular environment.
