Fibronectin is an extracellular matrix glycoprotein, while lamin is an intermediate filament that specifically provides support to the cell nucleus. Don’t confuse lamin with laminin (science hates us clearly); laminin is like fibronectin, an ECM glycoprotein and a major component of the basal lamina of basement membranes.
