WebExtracellular matrix proteins determine the structural nature of the tissue Tissues are defined by their extracellular matrix constituents. For instance, the cornea contains type I collagen filaments, which do not form fibrils of diameter greater than 5 nm; this is important in corneal transparency. WebCombined with cell adhesion molecules and extracellular matrix, cell junctions help hold animal cells together. Cell junctions are also especially important in enabling communication between neighboring cells via specialized protein complexes called communicating (gap) junctions.
