Disease

[FINC_HUMAN] Defects in FN1 are the cause of glomerulopathy with fibronectin deposits type 2 (GFND2) [MIM: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.^[1]

Function

[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.^[2] ^[3] ^[4] ^[5] 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.^[6] ^[7] ^[8] ^[9]

Publication Abstract from PubMed

The alternatively spliced type III extradomain B (EIIIB) of fibronectin (FN) is expressed only during embryogenesis, wound healing and tumorigenesis. The biological function of this domain is unclear. We describe here the first crystal structure of the interface between alternatively spliced EIIIB and its adjacent FN type III domain 8 (FN B-8). The opened CC' loop of EIIIB, and the rotation and tilt of EIIIB allow good access to the FG loop of FN-8, which is normally hindered by the CC' loop of FN-7. In addition, the AGEGIP sequence of the CC loop of EIIIB replaces the NGQQGN sequence of the CC' loop of FN-7. Finally, the CC loop of EIIIB forms an acidic groove with FN-8. These structural findings warrant future studies directed at identifying potential binding partners for FN B-8 interface, linking EIIIB to skeletal and cartilaginous development, wound healing, and tumorigenesis, respectively.
