Dimerization:
HOMODIMER INFORMATION There is experimental evidence for homo-dimerization METHOD Immunoprecipitation REFERENCES 10385123
HETERODIMER INFORMATION Forms heterodimers with delta Opioid Peptide Receptor. Dimerization results in altered ligand binding, potentiated signalling and altered internalization METHOD Immunoprecipitation REFERENCES 10385123
HETERODIMER INFORMATION Forms heterodimers with B2 Adrenoceptors. Heterodimerization results in altered internalization and MAPK signalling METHOD Immunoprecipitation REFERENCES 11134510
