FBN1

This gene encodes a member of the fibrillin family. The encoded protein is a large, extracellular matrix glycoprotein that serve as a structural component of 10-12 nm calcium-binding microfibrils. These microfibrils provide force bearing structural support in elastic and nonelastic connective tissue throughout the body. Mutations in this gene are associated with Marfan syndrome, isolated ectopia lentis, autosomal dominant Weill-Marchesani syndrome, MASS syndrome, and Shprintzen-Goldberg craniosynostosis syndrome.

Interaction

[Fibrillin-1]: Interacts with COL16A1 (PubMed:15165854). Interacts with integrin alpha-V/beta-3 (PubMed:15062093). Interacts with ADAMTS10; this interaction promotes microfibril assembly (PubMed:21402694). Interacts with THSD4; this interaction promotes fibril formation (By similarity). Interacts (via N-terminal domain) with FBLN2 and FBLN5 (PubMed:15790312, PubMed:17255108). Interacts with ELN (PubMed:15790312). Forms a ternary complex with ELN and FBLN2 or FBLN5 and a significant interaction with ELN seen only in the presence of FBLN2 or FBLN5 (PubMed:17255108). Interacts (via N-terminal domain) with LTBP2 (via C-terminal domain) in a Ca(+2)-dependent manner (PubMed:17293099). Interacts (via N-terminal domain) with LTBP1 (via C-terminal domain) (PubMed:17293099). Interacts with integrins ITGA5:ITGB1, ITGAV:ITGB3 and ITGAV:ITGB6 (PubMed:17158881, PubMed:12807887). Interacts (via N-terminal domain) with BMP2, BMP4, BMP7, BMP10 and GDF5 (PubMed:18339631). Interacts (via N-terminal domain) with MFAP2 and MFAP5 (PubMed:15131124). Interacts with ADAMTSL5 (PubMed:23010571). Interacts with MFAP4 (PubMed:26601954). Interacts (via N-terminal domain) with TNFSF11 in a Ca(+2)-dependent manner (PubMed:24039232). Interacts (via N-terminal domain) with EFEMP2; this interaction inhibits EFEMP2 binding to LOX and ELN (PubMed:17255108, PubMed:19349279, PubMed:19570982).
