Signaling pathways link extracellular cues to cellular responses, so that cells are able to adapt to the changes in the environment. The signals are processed as a series of molecular events in cells. Proteins responsible for detecting the signal are termed receptors or sensors, which are the first nodes in signaling transduction pathways.
How the receptors receive the signals and initiate the signaling transduction processes is under intensive research, especially ACE2, the entry point for coronaviruses (e.g., HCoV-NL63, SARS-CoV and SARS-CoV-2). CD BioSciences offers a complete portfolio of solutions for uncovering the mystery of receptors and sensors including identification and characterization of receptors and generation agonists and antagonists for receptors.
