A rat brain cDNA library was screened for clones homologous to the recently cloned mouse delta-opioid receptor (DOR-1). Among the clones isolated was Hyp 8-1, a clone with a unique nucleotide sequence capable of encoding a putative protein which is 57-58% identical to the amino acid sequences of the cloned delta, mu and kappa opioid receptors, indicating a close relationship of Hyp 8-1 with the opioid receptor family. Several cDNAs representing possible splice variants of Hyp 8-1 were also isolated. Binding studies of COS-7 cells transfected with clone Hyp 8-1 failed to demonstrate specific binding with several 3H-opioid ligands. In situ hybridization studies indicate that the mRNA for Hyp 8-1 is distributed discretely throughout the rat brain, in an overall pattern which is different from that of several other G-protein-coupled seven transmembrane receptors. Thus, it is likely that the Hyp 8-1 cDNA encodes a novel peptide receptor.
