Fn is a dimer of homologous monomers linked by S-S bond. Each monomer contains 3 types of modules: FnI, FnII and FnIII. Each module contains several numbered protein binding domains, i.e., 6FnI+1-2FnII is the gelatin binding domain (GBD).
Fn is a dimer of homologous monomers linked by S-S bond. Each monomer contains 3 types of modules: FnI, FnII and FnIII. Each module contains several numbered protein binding domains, i.e., FnI<sub>6</sub>-FnII<sub>1-2</sub>-FnI<sub>7-9</sub> is the gelatin binding domain (GBD).
Fibronectin (Fn) is a glycoprotein which binds extracellular matrix components like integrin, collagen, fibrin and others. It is a component of cell adhesion[1].
Relevance
Fn is associated with wound healing. Fn is a potential marker for radiation resistance.
Disease
Overexpression of Fn1 is associated with lung cancer.
