As a base for human transcriptome and functional genomics, we created the "full-length long Japan" (FLJ) collection of sequenced human cDNAs. We determined the entire sequence of 21,243 selected clones and found that 14,490 cDNAs (10,897 clusters) were unique to the FLJ collection. About half of them (5,416) seemed to be protein-coding. Of those, 1,999(More)
With the rapid increases in the amounts of sequence data for prokaryotic genomes, it has become important to develop systems for automated and accurate genome annotation. We present herein a novel ab initio gene identification system, GeneLook, that predicts protein-coding open reading frames (ORFs) with high sensitivity and specificity with no prior(More)
Remineralization of organic matter in deep-sea sediments is important in oceanic biogeochemical cycles, and bacteria play a major role in this process. Shewanella violacea DSS12 is a psychrophilic and piezophilic gamma-proteobacterium that was isolated from the surface layer of deep sea sediment at a depth of 5110 m. Here, we report the complete genome(More)
Liquid Chromatography Time-of-Flight Mass Spectrometry (LC-TOF-MS) is widely used for profiling metabolite compounds. LC-TOF-MS is a chemical analysis technique that combines the physical separation capabilities of high-pressure liquid chromatography (HPLC) with the mass analysis capabilities of Time-of-Flight Mass Spectrometry (TOF-MS) which utilizes the(More)
Characterization of orphan enzymes, for which the catalytic functions and actual substrates are still not elucidated, is a significant challenge in the postgenomic era. Here, we describe a general strategy for exploring the catalytic potentials of orphan monooxygenases based on direct infusion analysis by Fourier transform ion cyclotron resonance mass(More)
We have established a cAMP response element (CRE)-mediated reporter assay system for G-protein-coupled receptors (GPCRs) using an oriP-based estrogen-inducible expression vector and the B-cell line (GBC53 or GBCC71) that expresses EBNA-1 and is adapted to serum-free culture. GBC53 harbors a GAL4-ER expression unit and a CRE-luciferase gene in the genome,(More)
Granulocyte-colony stimulating factor (G-CSF) produced by nonhematopoietic malignant cells has been reported to be capable of inducing a leukemoid reaction in the host through intense stimulation of leukocyte production. Furthermore, this is frequently associated with aggressive tumor cell growth and a detrimental clinical outcome. In this study, we(More)

A peptide hormone analogue [Leu13]motilin has been produced in high yield by recombinant DNA techniques. The peptide was expressed from a multicopied [Leu13]motilin gene fused to a salmon growth hormone gene fragment. The monomeric [Leu13]motilin was obtained by treatment of the fusion protein with cyanogen bromide, carboxypeptidase A and B. [Leu13]motilin(More)
