General annotation (Comments)
| Function | Binding to cells via a high affinity receptor, laminin is thought to mediate the attachment, migration and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components. |
| Subunit structure | Laminin is a complex glycoprotein, consisting of three different polypeptide chains (alpha, beta, gamma), which are bound to each other by disulfide bonds into a cross-shaped molecule comprising one long and three short arms with globules at each end. |
| Subcellular location | Secreted › extracellular space › extracellular matrix › basement membrane. |
| Domain | The alpha-helical domains I and II are thought to interact with other laminin chains to form a coiled coil structure. Domains VI and IV are globular. |
| Sequence similarities | Contains 13 laminin EGF-like domains. Contains 1 laminin IV type B domain. Contains 1 laminin N-terminal domain. |
