Function
Extracellular matrix protein fibronectin (FN) plays an important role in cell adhesion. FN contains FN type I, II and III domains. The FN III repeat is generally about 90 amino acid long and to be composed of seven b-strands, forming two antiparallel b-sheets. In the C-terminal of human fibronectin region, there are 16 FN-III repeat domains. FN III domain derived proteins have been demonstrated to bind various proteins with high affinity.
The alternatively-spliced extra-domain B (EDB) of fibronectin represents one of the best characterized markers of angiogenesis. This domain of 91-aminoacids is completely identical between mouse and man, is virtually absent in normal adult tissues (exception made for the endometrium in the proliferative phase and some vessels of the ovaries), but is strongly expressed in most aggressive solid cancer types, with a prominent vascular and/or stromal pattern of expression.
