== Disease ==
[https://www.uniprot.org/uniprot/FINC_HUMAN FINC_HUMAN] Defects in FN1 are the cause of glomerulopathy with fibronectin deposits type 2 (GFND2) [MIM:[https://omim.org/entry/601894 601894]; also known as familial glomerular nephritis with fibronectin deposits or fibronectin glomerulopathy. GFND is a genetically heterogeneous autosomal dominant disorder characterized clinically by proteinuria, microscopic hematuria, and hypertension that leads to end-stage renal failure in the second to fifth decade of life.<ref>PMID:18268355</ref> 
== Function ==
[https://www.uniprot.org/uniprot/FINC_HUMAN FINC_HUMAN] Fibronectins bind cell surfaces and various compounds including collagen, fibrin, heparin, DNA, and actin. Fibronectins are involved in cell adhesion, cell motility, opsonization, wound healing, and maintenance of cell shape.<ref>PMID:8114919</ref> <ref>PMID:11209058</ref> <ref>PMID:15665290</ref> <ref>PMID:19379667</ref>   Anastellin binds fibronectin and induces fibril formation. This fibronectin polymer, named superfibronectin, exhibits enhanced adhesive properties. Both anastellin and superfibronectin inhibit tumor growth, angiogenesis and metastasis. Anastellin activates p38 MAPK and inhibits lysophospholipid signaling.<ref>PMID:8114919</ref> <ref>PMID:11209058</ref> <ref>PMID:15665290</ref> <ref>PMID:19379667</ref>

== Publication Abstract from PubMed ==
Staphylococcus aureus can adhere to and invade endothelial cells by binding to the human protein fibronectin (Fn). FnBPA and FnBPB, cell wall-attached proteins from S. aureus, have multiple, intrinsically disordered, high-affinity binding repeats (FnBRs) for Fn. Here, 30 years after the first report of S. aureus/Fn interactions, we present four crystal structures that together comprise the structures of two complete FnBRs, each in complex with four of the N-terminal modules of Fn. Each approximately 40-residue FnBR forms antiparallel strands along the triple-stranded beta-sheets of four sequential F1 modules ((2-5)F1) with each FnBR/(2-5)F1 interface burying a total surface area of approximately 4,300 A(2). The structures reveal the roles of residues conserved between S. aureus and Streptococcus pyogenes FnBRs and show that there are few linker residues between FnBRs. The ability to form large intermolecular interfaces with relatively few residues has been proposed to be a feature of disordered proteins, and S. aureus/Fn interactions provide an unusual illustration of this efficiency.
