Molecular cloning identified complementary DNA species, from a rat ventral midbrain library, encoding apparent splice variants of the N-methyl-D-aspartate (NMDA) receptor NMDAR1 (which we now term NR1a). Sequencing revealed that one variant, NR1b, differs from NR1a by the presence of a 21-amino acid insert near the amino end of the N-terminal domain and by(More)
The complete coding sequence from a human creatine transporter cDNA was isolated from a kidney library. This transporter is a member of a superfamily of proteins which includes the family of Na(+)- and Cl(-)-dependent transporters responsible for the uptake of certain neurotransmitters (e.g. dopamine, GABA, serotonin, and norepinephrine), and amino acids(More)
A rat dopamine (DA) transporter complementary DNA has been isolated with combined complementary DNA homology and expression approaches. The DA transporter is a 619-amino acid protein with 12 hydrophobic putative membrane-spanning domains and homology to the norepinephrine and gamma-aminobutyric acid transporters. The expressed complementary DNA confers(More)
The transformer (tra) gene regulates female somatic sexual differentiation and has no known function in males. It gives rise to two sizes of RNA, one non-sex-specific and one female-specific. These two RNAs are shown to be present throughout the life cycle, and related by the use of alternative first intron splice acceptor sites. The non-sex-specific RNA(More)
mu opiate receptors recognize morphine with high affinity. A 2.1-kb rat brain cDNA whose predicted translation product displays 63% identity with recently described delta and kappa opiate receptor sequences was identified through polymerase chain reaction and cDNA homology approaches. This cDNA recognizes a 10.5-kb mRNA that is expressed in thalamic(More)
We employed the polymerase chain reaction and genomic DNA library screening to clone novel human genes, GPR9 and GPR10, and a rat gene, GPR14. GPR9, GPR10, and GPR14 each encode G protein-coupled receptors. GPR10 and GPR14 are intronless within their coding regions, while GPR9 contains at least one intron. The receptor encoded by GPR9 shares the highest(More)
Molecular heterogeneity of kainate-selective glutamate receptor subunits GluR5 and GluR6 was revealed by identification of a human cDNA, GluR5-1d, and a murine cDNA, GluR6-2, that each encode subunits with novel carboxy-terminal sequences. Both GluR5-1d and GluR6-2 appear to be generated by alternative splicing at analogous sites 14 codons following the(More)
