Scientists have found that extracellular matrix components may induce specific gene expression in embryonic tissues such as the liver and testis.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 are involved in cell adhesion and signal transduction. They bind to extracellular matrix components such as fibronectin, collagen, and laminin, and thereby regulate cell behavior, including gene expression. Integrins are known to be involved in inducing specific gene expression in embryonic tissues such as the liver and testis through direct communication between the extracellular matrix and developing cells. Therefore, it is most likely that integrins would be involved in this kind of induction.
