We have sequenced and annotated the genome of fission yeast (Schizosaccharomyces pombe), which contains the smallest number of protein-coding genes yet recorded for a eukaryote: 4,824. The centromeres are between 35 and 110 kilobases (kb) and contain related repeats including a highly conserved 1.8-kb element. Regions upstream of genes are longer than in(More)
Streptomyces coelicolor is a representative of the group of soil-dwelling, filamentous bacteria responsible for producing most natural antibiotics used in human and veterinary medicine. Here we report the 8,667,507 base pair linear chromosome of this organism, containing the largest number of genes so far discovered in a bacterium. The 7,825 predicted genes(More)
Leishmania species cause a spectrum of human diseases in tropical and subtropical regions of the world. We have sequenced the 36 chromosomes of the 32.8-megabase haploid genome of Leishmania major (Friedlin strain) and predict 911 RNA genes, 39 pseudogenes, and 8272 protein-coding genes, of which 36% can be ascribed a putative function. These include genes(More)
Vascular permeability factor (VPF) is a 40-kilodalton disulfide-linked dimeric glycoprotein that is active in increasing blood vessel permeability, endothelial cell growth, and angiogenesis. These properties suggest that the expression of VPF by tumor cells could contribute to the increased neovascularization and vessel permeability that are associated with(More)
Somatostatin is a 14 amino acid peptide hormone that is synthesized as part of a larger precursor, preprosomatostatin, which comprises about 120 amino acids. The overall organization of the precursor is conserved in many species in that it consists of a signal peptide followed by a proregion of 90-100 amino acids and the mature hormone is located at the(More)
Glucagon, a polypeptide hormone of 29 amino acids, is synthesized in the islets of Langerhans and immunoreactive forms of the molecule have been found in several tissues. Like many other polypeptide hormones, glucagon is synthesized via a larger precursor molecular, proglucagon; however, estimates of its size vary considerably and the biosynthetic(More)
Translation of poly(A)-containing RNA from the female fat body of Drosophila melanogaster in a rabbit reticulocyte cell-free system results in the synthesis of previtellogenin polypeptides (PVs) having higher apparent molecular weights (46,000 and 45,000) than the forms seen after an in vivo pulse labeling. However, when this RNA is translated in the(More)
Two variants in immunoglobulin heavy chain production, derived from the MPC 11 mouse myeloma cell line, make short heavy (H) chains with identical precise deletions of the CH3 domain. The CH3 domain is expressed in the H chain mRNA from both variants. Although in vitro translation of this mRNA produces one H chain species, deleted heavy chains are secreted(More)
I Fragile X syndrome, a frequent form of inherited mental retardation, results from the unstable expansion of a cryptic CGG repeat within the 5' UTR region of the FMR1 gene. The CGG repeat is normally polymorphic in length, and the content is frequently interrupted by AGG triplets. These interruptions are believed to stabilize the repeat, and their absence,(More)
We have engineered GH3 cells with reporter genes under control of the growth hormone and prolactin promoters and measured protein production. The results indicate very low level production of reporter proteins from the cells regardless of the promoter used to drive expression. This was surprising in light of the observation that the cells still produced(More)
