Question

Quizplus · Accepted Answer

G proteins act as the middlemen in signal transduction by binding to the activated receptor and transducing the signal to the next protein in the pathway. This process ultimately leads to a cellular response, such as gene expression or enzyme activation. G proteins do not bind extracellular signal molecules, convert ATP to cATP, or phosphorylate relay molecules in the pathway.
