Intro to Pharmacology
G-protein coupled receptors (GPCRs) are a large family of membrane proteins that play a crucial role in cellular signaling by transmitting signals from outside the cell to the inside. These receptors are activated by various ligands, such as hormones and neurotransmitters, leading to the activation of intracellular G-proteins, which then initiate a cascade of downstream signaling events. GPCRs are involved in numerous physiological processes and are important targets for drug development due to their central role in drug-receptor interactions.
congrats on reading the definition of g-protein coupled receptors. now let's actually learn it.
