Receptor Proteins

Receptor proteins are a class of functional proteins widely present on cell membranes or within cells. They specifically recognize and bind to ligands (such as hormones, cytokines, antibodies, drugs, etc.) and convert extracellular signals into intracellular biological effects through signal transduction. They are key molecules that enable cells to sense and respond to microenvironmental changes and regulate life activities. Recombinant receptor proteins are expressed and purified using genetic engineering technology in systems such as mammalian cells and insect cells. They feature native-like conformation, high purity, stable activity, and good batch-to-batch consistency, thereby mimicking the physiological functions of receptors in the body. These proteins are widely used in target validation, ligand screening, drug affinity measurements, signaling pathway research, and the development of in vitro diagnostic reagents. They play a central role in drug discovery, immunotherapy, and basic medical research, serving as essential tool proteins in biomedicine and life science research.
