True or false? The structure type proteins that best characterize ECM are collagen and laminin.

The accurate characterization of extracellular matrix (ECM) proteins highlights that while collagen and laminin are indeed significant components, they represent just a subset of the numerous proteomic components present in the ECM. The ECM is a complex network primarily composed of various proteins, including glycoproteins, proteoglycans, and several types of collagens, which altogether contribute to its structural integrity, function, and the regulation of cellular activities.

Collagen, the most abundant protein in the ECM, provides tensile strength and structural support. Laminin plays a crucial role in cell adhesion, differentiation, and migration. However, the ECM also contains other essential proteins such as fibronectin, elastin, and different glycoproteins that are vital for its diverse functions. As a result, stating that collagen and laminin solely characterize ECM structure is an oversimplification, making the assertion false.
