【 摘 要 】
The human μ-opioid receptor cDNA from which the 32 amino-terminal codons were substituted by the Saccharomyces cerevisiae α-mating factor signal sequence has been expressed in the methylotrophic yeast Pichia pastoris using the host promoter of the alcohol oxidase-1 gene. Cell membranes exhibited specific and saturable binding of the opioid antagonist [3H]diprenorphine (K d = 0.2 nM and B max = 400 fmol/mg protein or 800 sites/cell). Competition studies with non-selective, and μ-, δ- and κ-selective opioid agonists and antagonists revealed a typical μ-opioid receptor binding profile, suggesting proper folding of the protein in yeast membranes.
