1. Fibrillin builds the oxytalan fibers, which causes the elastic behavior.2. The zonules are primarily made of fibrillin , a connective tissue protein. 3. There is no complete, high-resolution structure of fibrillin -1. 4. Both can be caused by mutations in the gene encoding a protein called fibrillin . 5. Reducing the level of normal fibrillin 1 causes a Marfan-related disease in mice. 6. Impressively, in fibrillin -1 and fibrillin-2, 43 cbEGF modules have been found. 7. Impressively, in fibrillin-1 and fibrillin -2, 43 cbEGF modules have been found. 8. The microfibrils that are made up of fibrillin protein are responsible for different cell-matrix interactions in the human body. 9. Mutations in the fibrillin gene lead to the condition Marfan syndrome, and consequences include an increased risk of lens dislocation. 10. Marfan's is a highly variable but potentially deadly disorder of connective tissue involving a defect in a protein called fibrillin .
