And one example is fibronectin. So Fibronectin is basically a peripheral glycoprotein that is actually attached onto a transmembrane protein known as Integrin, or Integrin. Now, fibronistin is not only anchored onto the Integrin, but the fibronectin is actually itself anchored onto the collagen fibers found in the extracellular matrix. On top of that, the Integrin is actually also attached onto the actin filaments that are found inside the cytoplasma, inside the cytoskelet and the cytoplasm. So, because of all these anchoring positions and attachment points, fibro nectin doesn't actually move. It moves very slowly.
