Fibrin .
Fibrillin is a glycoprotein , which is essential for the formation of elastic fibers found in connective tissue .[2] extracellular matrix by fibroblasts and becomes incorporated into the insoluble microfibrils, which appear to provide a scaffold
for deposition of elastin .[3]
Clinical aspects [ edit ]
Marfan syndrome is a genetic disorder of the connective tissue caused by defected FBN1 gene. Mutations in FBN1 and FBN2 are also sometimes associated with adolescent idiopathic scoliosis .[4]
Fibrillin-1 [ edit ]
Fibrillin-1 is a major component of the microfibrils that form a sheath surrounding the amorphous elastin . It is believed that the microfibrils are composed of end-to-end polymers of fibrillin. To date, 3 forms of fibrillin have been described. The fibrillin-1 protein was isolated by Engvall in 1986,[5] Marfan syndrome .[6] [7]
This protein is found in humans, and its gene is found on chromosome 15. At present more than 1500 different mutations have been described.[1] [7]
Structure [ edit ]
There is no complete, high-resolution structure of fibrillin-1. Instead, short fragments have been produced recombinantly and their structures solved by X-ray crystallography or using NMR spectroscopy. A recent example is the structure of the fibrillin-1 hybrid2 domain, in context of its flanking calcium binding epidermal growth factor domains, which was determined using X-ray crystallography to a resolution of 1.8 Å.[1]
Fibrillin-2 [ edit ]
Fibrillin-2 was isolated in 1994 by Zhang[8] elastogenesis . Mutations in the fibrillin-2 gene have been linked to Beals syndrome .
Fibrillin-3 [ edit ]
More recently, fibrillin-3 was described and is believed to be located mainly in the brain.[9]
Fibrillin-4 [ edit ]
Fibrillin-4 was first discovered in zebrafish, and has a sequence similar to fibrillin-2.[10]
