Target Information

Fibronectin is a disulfide-bonded dimer with a molecular weight range of 230–250 kDa. In the extracellular matrix of connective tissues and vessels, fibronectin exists as an insoluble protein cross-linked by interchain disulfide bonds forming high molecular mass polymers. It is abundant during embryonic development and tissue remodeling, and also present at high concentrations as a soluble plasma protein.

Fibronectin consists of repeating modules forming domains for interaction with fibronectin itself, other matrix components (e.g., collagen and heparin), and cell receptors (e.g., integrins). It plays crucial roles in cell adhesion and migration processes including embryogenesis, wound healing, blood coagulation, host defense, and metastasis. Elevated fibronectin expression is associated with non-small cell lung carcinoma, enhancing tumorigenicity and resistance to apoptosis induced by chemotherapeutic agents. The gene encoding fibronectin has three regions subject to alternative splicing, potentially producing up to 20 transcript variants.
