Four ECM ubiquitous protein components, each of which comprises multiple, distinct, repeating domains, are found in basal laminae. Given below are a list of some extracellular matrix (ECM) proteins in column A and their characteristics in column B.

Column A

Column B

a. Type IV collagen

i. a large multidomain proteoglycan that binds to and cross-links many ECM components and cell-surface molecules.

b. Laminins

ii. a rodlike molecule that cross-links type IV collagen, perlecan, and laminin, which

helps incorporate other components into the ECM and also stabilizes basal laminae.

c. Perlecan

iii. a family of multi-adhesive, cross-shaped proteins that form a fibrous two-dimensional network with type IV collagen and that also bind to integrins and other adhesion

receptors.

d. Nidogen

iv. trimeric molecules with both rodlike

and globular domains that form a two-dimensional network.

Which one of the following is the most appropriate match?
