G Protein-Coupled Receptors: Gateways to Cellular Signaling

Rodriguez Taylor

G Protein-Coupled Receptors (GPCRs) are a vital class of cell surface receptors that play a crucial role in cellular signaling. These receptors act as molecular switches, transmitting signals from extracellular stimuli to the cell's interior, initiating a wide array of cellular responses. GPCRs are involved in processes such as sensory perception, immune responses, hormonal regulation, and neurotransmission. This study explores the significance of GPCRs in cellular signaling, their structure, activation mechanisms, and the diverse physiological processes they regulate.
