Structural highlights

1qgb is a 1 chain structure with sequence from Homo sapiens. Full experimental information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:Solution NMR, 24 models

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

Multiple sites within the N-terminal domain (1-5F1) of fibronectin have been implicated previously in fibronectin matrix assembly, heparin binding, and binding to cell surface proteins of pathogenic bacteria. The solution structure of 1F1(2)F1, the N-terminal F1 module pair from human fibronectin, has been determined using NMR spectroscopy. Both modules in the pair conform to the F1 consensus fold. In 4F1(5)F1, the only other F1 module pair structure available, there is a well-defined intermodule interface; in 1F1(2)F1, however, there is no detectable interface between the modules. Comparison of the backbone 15N-{1H} NOE values for both module pairs confirms that the longer intermodule sequence in 1F1(2)F1 is flexible and that the stabilization of the 4F1 C-D loop observed in 4F1(5)F1, as a result of the intermodule interface, is not observed in 1F1(2)F1.
