GPCR Superfamily

G-protein coupled receptors (GPCRs) are a large class of proteins found on cell surfaces that detect molecules like hormones, neurotransmitters, and light. When these molecules bind to GPCRs, they trigger internal processes inside the cell, acting as communication switches. This family of proteins is crucial for many bodily functions, including senses like vision and smell, immune responses, and regulating mood. Their versatility and importance make GPCRs a key focus in drug development, as targeting these receptors can help treat numerous health conditions.
