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?

Question

Quizplus · Accepted Answer

Integrins are transmembrane proteins that serve as receptors for extracellular matrix components, allowing direct communication between the matrix and developing cells. This makes them the most likely candidate to be involved in inducing specific gene expression in embryonic tissues such as the liver and testis. Actins, fibronectins, and collagens are all important components of the extracellular matrix, but they do not serve as receptors for cellular signaling.
