Receptor proteins embeded in the cell membrane that transmit signals between the Extracellular Matrix and the cytoplasm are called ____
|
|
Collagens
|
|
|
Glycoproteins
|
|
|
Integrins
|

Peripheral Proteins

Explanation:
Detailed explanation-1: -Extracellular matrix proteins bind to integrin-cell surface receptors to trigger signaling pathways involved in cell spreading, cytoskeletal rearrangement, cell proliferation, survival and migration.
Detailed explanation-2: -Integrins are a class of receptors that comprise heterodimeric type I transmembrane proteins consisting of and subunits. These subunits contain a large extracellular domain, a single transmembrane domain, and a short cytoplasmic tail.
Detailed explanation-3: -The laminin receptor is a non-integrin cell surface receptor that helps to mediate high affinity interactions between cells and components of the extracellular matrix such as laminin, fibronectin, collagen, and elastin (16–19).
