Collagen is a primary structural protein found in the ECM of animal tissues. Proteoglycans in the matrix help to retain water and provide cushioning. The ECM facilitates cell communication through signaling molecules. Matrix metalloproteinases (MMPs) are enzymes that degrade ECM components during tissue remodeling. Review Questions What are the main components of the extracellular matrix? How does collagen contribute to the function of animal tissues? Why are proteoglycans important in the ECM?
