#Unit 4. Cell Communication and Cell Signaling
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. |
