In epidermal wounds, precursor laminin 5 (alpha3beta3gamma2) is deposited in the provisional basement membrane (PBM) before other BM components. Precursor laminin 5 contains G4/5 globular domains at the carboxyl terminus of the alpha3 chain. Here, the function of G4/5 was evaluated in deposition of laminin 5.

In large part, this is because Mabs can identify the function of the adhesion components within the context of the complex ECM or the cell surface. There are now many isoforms of laminin, collagen, and other ECM components that have been identified by molecular and Mab approaches.

The four toxins comprise two 57 residue and two 59 residue isoforms. The long toxins possess a Lys-Gln N-terminal extension lacked by the short toxins.
