1.Fibronectin is a connector molecule that links _____ on the cell surface to _____ in the extracellular matrix
a.Integrins/actin
b.Actin/Integrins
c.Integrins/collagen
d.Collagen/integrins
Homework Answers
Answer
Option C the right answer as fibronectin is a connector molecule that links integrin on the cell surface to collagen in the extracellular matrix.
Fibronectin also links with integrin on the cell surface to fibrin or heparan sulfate proteoglycan in the extracellular matrix that helps cells to adhere firmly with ECM.

The tri-peptide sequence, RGD, is found in the extracellular matrix (ECM) protein fibronectin and serves as a recognition sequence for integrins (integral membrane proteins) in the cell wall. The integrin-RGD interaction anchors cells to the ECM.

4) In migrating cells, ______ are stable links between the ECM and the actin cytoskeleton 5) Which one of the following is true? All integrin-containing adhesion complexes have the same cytoplasmic components the spatial organization of integrin-containing adhesion complexes varies depending on the nature of ECM contacting the cell integrin-containing adhesion complexes connect microtubules to the ECM integrin activation involves conformational changes of the extracellular but not intracellular domains of integrins What protective function does calcium gating serve in gap...

1. Integrins are surface / cytoplasmic proteins that play an important role in holding together 2. Regulation of cell adhesion by integrins demonstrates that cell adhesion is modulated which of the following strategies: a. changes in the activation state an adhesion protein. b. changes in extracellular phosphorylation of an adhesion protein. c. changes in disulfide bonding within an adhesion protein. d. changes in the number of adhesion proteins on the cell surface. 3. True / False Integrins only bind their...

I got this question in an exam : How does the extracellular matrix interact with cells : a) with proteoglycans b) with collagen c) with fibronectins d) with tight junctions I answered a because the proteoglycans constitute the network that holds the cells and extracellular proteins. I ruled out fibronectins because they form a dimer with integrins to connect collagen and the cell, which is just an example of an interaction. But proteoglycans are the fibres which collagen is embedded...
