Question

Quizplus · Accepted Answer

G-proteins function as relay molecules in cell signaling pathways, transmitting signals from activated receptors to target molecules inside the cell. They are heterotrimeric, meaning they consist of three subunits (alpha, beta, and gamma), not two, and they are not directly associated with steroid receptors, which typically act as transcription factors and bind directly to DNA.
