摘要:
A human &mgr; opiate receptor cDNA has been identified from a cerebral cortical CDNA library using sequences from the rat &mgr; opiate receptor CDNA. The human &mgr; opiate receptor (h&mgr;OR1) shares 95% amino acid identity with the rat sequence. The expressed &mgr;OR1 recognizes tested opiate drugs and opioid peptides in a sodium- and GTP-sensitive fashion with affinities virtually identical to those displayed by the rat &mgr; opiate receptor. Effects on cyclic AMP are similar to those noted for the rat &mgr; opiate receptor. Overlapping genomic clones spanning 50 kilobasepairs and hybridizing with the h&mgr;OR1 cDNA contains exon sequences encoding the entire open reading frame of the human A opiate receptor are described. Analysis of hybridization to DNA prepared from human rodent hybrid cell lines and chromosomal in situ hybridization studies indicate localization to 6q24-25. An MspI polymorphism, producing a 3.7 kb band, is being used to assess this gene's involvement in neuropsychiatric disorders involving opiatergic systems.
