Dimerization of GPCRs have significant functional consequences, affecting ligand binding affinity, receptor trafficking as well as signaling specificity of downstream signaling pathways. This animation shows a full-atomic molecular dynamics simulation of the rhodopsin homodimer observed in an explicit membrane environment.PS: These simulations could only be imagined earlier. (Protein-protein interactions govern a large number of biological processes. A number of cell surface and nuclear receptors mediate their actions via dimerization.)[MEDIA=youtube]DhoXLOMVaPk[/MEDIA]</blockquote>
