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. Gamma-1 is a subunit of laminin-1 (EHS laminin), laminin-2 (merosin), laminin-3 (S-laminin), laminin-4 (S-merosin), laminin-6 (K-laminin) and laminin-7 (KS-laminin).

Subcellular location

Secreted › extracellular space › extracellular matrix › basement membrane.

Tissue specificity

Found in the basement membranes (major component).

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 11 laminin EGF-like domains.

Contains 1 laminin IV type A domain.

Contains 1 laminin N-terminal domain.
