Receptor clustering and dimerization
Understand receptor clustering and dimerization
A ligand-target interaction often changes in affinity and kinetics when the receptor shifts from a monomeric to a dimeric state, or when it forms clusters. This can be exploited to better understand your biological system. Investigate how drugs induce or prohibit dimerization or clustering by following the ligand binding, or label some ligands with quenchers* and study changes in proximity over time.
