Laminins are the most abundant glycoprotein in the basement membrane and has binding domains for both ECM and cell-surface receptors. In the basal membrane, polymers of laminin and collagen type IV (COL4s) form tightly bound networks. Laminins can also mediate the attachment of cells to connective tissue substrates.
