Scientists have found that extracellular matrix components may induce specific gene expression in embryonic tissues such as the liver and testes. For this to happen there must be direct communication between the extracellular matrix and the developing cells. Which kind of transmembrane protein would most likely be involved in this kind of induction?
A) integrins
B) collagens
C) actins
D) fibronectins

Question

Quizplus · Accepted Answer

Integrins are transmembrane proteins that act as receptors for extracellular matrix components such as fibronectin and collagen. They can transmit signals from the ECM to the developing cells and influence gene expression, differentiation, and cell proliferation. Therefore, integrins are the best choice for the kind of induction described in the question.
