Fibrillin-1 is a ubiquitous protein mostly expressed in muscles in its monomeric form. The monomers then polymerize to form the 10 to 12nm of diameter '''microfibrils'''. In the microfibrils the fibrillin-1 is associated to various proteins such as [[MAGP-1]], [[MAGP-2]], [[fibulin 2]] and [[fibulin 5]], [[elastin]], [[versicane]] and [[LTBP-1]]. Those microfibrils constitute the elastic and non-elastic human connective tissues such as the dermis or the organs. This protein plays an important role in the [https://en.wikipedia.org/wiki/Cytokine cytokine] and growth factor regulation. <ref>Julien Wipff, Yannick Allanore, and Catherine Boileau. (2009).
