Signals Between the ECM and the Cytoskeleton May Be Transmitted

Question

Signals between the ECM and the cytoskeleton may be transmitted by
A) fibronectin.
B) proteoglycans.
C) integrins.
D) collagen.
E) middle lamella.

Accepted Answer

Integrins are receptor proteins found on the surface of cells that bind to the extracellular matrix, allowing for communication between the ECM and the cytoskeleton. Fibronectin, proteoglycans, collagen, and middle lamella are all components of the ECM, but do not directly transmit signals to the cytoskeleton.
