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. Ref.5

Laminin-3 (S-laminin) regulates the formation of motor nerve terminals. Ref.5

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. Beta-2 is a subunit of laminin-3 (laminin-121 or S-laminin), laminin-4 (laminin-221 or S-merosin), laminin-7 (laminin-321 or KS-laminin), laminin-9 (laminin-421), laminin-11 (laminin-521), laminin-14 (laminin-423) and laminin-15 (laminin-523).

Subcellular location

Secreted › extracellular space › extracellular matrix › basement membrane.

Tissue specificity

Neuromuscular synapse and kidney glomerulus.

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.
