The mouse inbred line C57BL/6J is widely used in mouse genetics and its genome has been incorporated into many genetic reference populations. More recently large initiatives such as the International Knockout Mouse Consortium (IKMC) are using the C57BL/6N mouse strain to generate null alleles for all mouse genes. Hence both strains are now widely used in(More)
Members of the three kingdoms of life contain tRNA genes with introns. The introns in pre-tRNAs of Bacteria are self-splicing, whereas introns in archaeal and eukaryal pre-tRNAs are removed by splicing endonucleases. We have studied the structures of the endonucleases of Archaea and the architecture of the sites recognized in their pre-tRNA substrates.(More)
In 2007, the International Knockout Mouse Consortium (IKMC) made the ambitious promise to generate mutations in virtually every protein-coding gene of the mouse genome in a concerted worldwide action. Now, 5 years later, the IKMC members have developed high-throughput gene trapping and, in particular, gene-targeting pipelines and generated more than 17,400(More)
The function of the majority of genes in the mouse and human genomes remains unknown. The mouse embryonic stem cell knockout resource provides a basis for the characterization of relationships between genes and phenotypes. The EUMODIC consortium developed and validated robust methodologies for the broad-based phenotyping of knockouts through a pipeline(More)
The laboratory mouse is the premier animal model for studying human disease and thousands of mutants have been identified or produced, most recently through gene-specific mutagenesis approaches. High throughput strategies by the International Knockout Mouse Consortium (IKMC) are producing mutants for all protein coding genes. Generating a knock-out line(More)
RNA aptamers that specifically bind dopamine have been isolated by in vitro selection from a pool of 3.4 x 10(14) different RNA molecules. One aptamer (dopa2), which dominated the selected pool, has been characterized and binds to the dopamine affinity column with a dissociation constant of 2.8 microM. The specificity of binding has been determined by(More)
The orphan G protein-coupled receptor 37 (GPR37) is a substrate of parkin; its insoluble aggregates accumulate in brain samples of Parkinson's disease patients. We report here that GPR37 interacts with the dopamine transporter (DAT) and modulates DAT activity. GPR37 and DAT were found colocalized in mouse striatal presynaptic membranes and in transfected(More)
A cDNA sequence encoding a putative peptide-specific G-protein-coupled receptor (GPR37) was isolated from a set of human brain frontal lobe expressed sequence tags. The GPR37 cDNA predicts a single open reading frame coding for a 613-amino-acid protein with seven hydrophobic transmembrane domains. The GPR37 genomic sequence was mapped to chromosome 7q31,(More)
GPR37 is an orphan G protein-coupled receptor expressed in mammalian brain, and its insoluble aggregates are found in the brain samples of juvenile Parkinson's disease patients. We have produced a Gpr37 knock-out mouse strain and identified several phenotypic features that are similar to those reported for mutants of genes encoding components of synaptic(More)
