Fibronectin

Fibronectin (FN1, chr2q35) is a major ECM glycoprotein; plasma FN is a soluble dimer from hepatocytes; cellular FN assembles into insoluble fibrils. Integrin α5β1 and αvβ3 bind via RGD → cell adhesion, migration, and fibrosis. Central provisional matrix scaffold in wound healing.

Also known as: FN, FN1, plasma fibronectin, cellular fibronectin, EDA fibronectin, EDB fibronectin
