【Abstract】 As for the μ opioid receptor, there are some disputes about the domains involved in the selective recognition of ligands, the relative spatial orientation of the amino acids within the TM affect the affinities of selective ligands. Regulation of opioid receptor activities does not appear to involve in their ability to promote the association of GTP onto the G proteins and the subsequent dissociation of heterotrimers. It is not very clear if phosphorylation correlates with agonist induced receptor desensitization. The celluar processing of μ opioid receptors requires the formation of multiple protein complexes, it is clear that interactions of ubiquitous transcriptional factors determine gene transcription.更多还原
