WebAlternatively, the target protein may be engaged in specific interactions with an immobilized ligand, but other regions of the protein surface that are outside the specific ligand-binding site may interact with neighboring ligands on the same bead (Figure 1b). This would bias the screening towards sequences that are capable of such nonspecific ...

WebSep 15, 2015 · A G protein-biased ligand at the mu-opioid receptor is potently analgesic with reduced gastrointestinal and respiratory dysfunction compared with morphine ... The advent of biased agonism at G protein-coupled receptors has expanded our understanding of intracellular signaling and highlighted the concept that certain ligands are able to ... WebMethods: The archetypical µ-opioid receptor agonist morphine and, separately, the G-protein-biased µ-opioid receptor agonist oliceridine were administered to mice. These drugs were used in models of acute analgesia, analgesic tolerance, opioid-induced hyperalgesia, reward, and physical dependence. mybatis script if test
