The present invention relates to novel mammalian biogenic amine receptor proteins and genes that encode such proteins. The invention is directed toward the isolation and characterization of mammalian trace amine receptor proteins. The invention specifically provides isolated complementary DNA copies of mRNA corresponding to rat and human homologues of a mammalian trace amine receptor gene. Also provided are recombinant expression constructs capable of expressing the mammalian trace amine receptor genes of the invention in cultures of transformed prokaryotic and eukaryotic cells, as well as such cultures of transformed cells that synthesize the mammalian trace amine receptor proteins encoded therein. The invention also provides methods for screening compounds in vitro that are capable of binding to the mammalian trace amine receptor proteins of the invention, and further characterizing the binding properties of such compounds and functional consequences thereof in comparison with known trace amine receptor agonists and antagonists. Improved methods of pharmacological screening are provided thereby.
本发明涉及新型哺乳动物生物胺受体蛋白和编码此类蛋白的基因。本发明的目的是分离和鉴定哺乳动物痕量胺受体蛋白。本发明特别提供了与哺乳动物痕量胺受体基因的大鼠和人类同源物相对应的 mRNA 的分离互补 DNA 拷贝。本发明还提供了重组表达构建体,这些构建体能够在转化的原核细胞和真核细胞培养物中表达本发明的哺乳动物痕量胺受体基因,以及合成其中编码的哺乳动物痕量胺受体蛋白的转化细胞培养物。本发明还提供了在体外筛选能与本发明的哺乳动物痕量胺受体蛋白结合的化合物的方法,以及与已知的痕量胺受体激动剂和拮抗剂相比,进一步鉴定这些化合物的结合特性及其功能后果的方法。由此提供了改进的药理学筛选方法。
