Function

Fibronectin (Fn) is a glycoprotein which binds extracellular matrix components like integrin, collagen, fibrin and others. It plays an important role in cell adhesion, migration and differentiation^[1][2]. In addition, Fn is also important for the adherence of pathogens to host tissues and the linking between proteins and cells^[3].

Relevance

Fn is associated with wound healing. Fn is a potential marker for radiation resistance.

Disease

Overexpression of Fn1 is associated with lung cancer^[4].
