| Main Title | Information about hetero oligomer between CXCR4 chemokine receptor and opioid receptor ( OPR), and interfaces of CXCR4 |
| GPCR Class | A |
| GPCR Subfamily | Chemokine |
| GPCR Subtype | CXCR4 |
| GPCR Name | CXCR4 |
| Partner Class | A |
| Partner Subfamily | Opioid |
| Partner Subtype | kappa |
| Partner Name | kappaOPR |
| Evidence | Experiment |
| Annotations | Both mu and delta ORs cross-desensitize CCR1, CCR2, CCR5, but not CXCR4, while kappa OR is able to cross-desensitize CXCR4, and this phenomenon is bi-directional. Chemotactic responses by kappa OR activation are reduced by activation of CXCR4 in advance. In addition, calcium mobilization assays show these cross-desensitization processes occur within seconds of receptor activation, and target receptor internalization is not responsible for desensitization between these receptors. |
