HOMODIMER INFORMATION There is experimental evidence for homo-dimerization METHOD Fluorescence Resonance Energy Transfer (FRET) REFERENCES 11682068
HOMODIMER INFORMATION There is experimental evidence for homo-dimerization METHOD Immunoprecipitation REFERENCES 10860933
HETERODIMER INFORMATION Forms heterodimers with Dopamine D3 Receptors. Dimerization results in an Increased affnity and potency for agonists and antagonists METHOD Functional reconstitution REFERENCES 11373283
HETERODIMER INFORMATION Forms heterodimer with Somatostatin SST5 Receptor. Dimerization results in increased ligand binding affnity and enhanced signalling METHOD Photobleaching Fluorescence Resonance Energy Transfer (FRET) REFERENCES 10753124
HETERODIMER INFORMATION Forms heterodimers with Adenosine A2A Receptor. Heterodimerization results in co-desensitization and co-internalization of the receptors METHOD Immunoprecipitation REFERENCES 11872740
