The Yeast Proteome Database (YPDtrade mark) has been for several years a resource for organized and accessible information about the proteins of Saccharomyces cerevisiae. We have now extended the YPD format to create a database containing complete proteome information about the model organism Caenorhabditis elegans (WormPDtrade mark). YPD and WormPD are(More)
The Yeast Proteome Database (YPD) is a model for the organization and presentation of comprehensive protein information. Based on the detailed curation of the scientific literature for the yeast Saccharomyces cerevisiae, YPD contains more than 50 000 annotations lines derived from the review of 8500 research publications. The information concerning each of(More)
In this study, we examined yeast proteins by two-dimensional (2D) gel electrophoresis and gathered quantitative information from about 1,400 spots. We found that there is an enormous range of protein abundance and, for identified spots, a good correlation between protein abundance, mRNA abundance, and codon bias. For each molecule of well-translated mRNA,(More)
An improved method of two-dimensional gel electrophoresis has been developed which produces high resolution, reproducible images suitable for computer analysis. In the images that are presented, more than 800 proteins have been resolved without significant overlap, and many more proteins can be detected after longer exposures. To establish the usefulness of(More)
The BioKnowledge Library is a relational database and web site (http://www.proteome.com) composed of protein-specific information collected from the scientific literature. Each Protein Report on the web site summarizes and displays published information about a single protein, including its biochemical function, role in the cell and in the whole organism,(More)
Studies of growth regulation and cellular transformation will be assisted by the identification of proteins that are preferentially synthesized in dividing cells. The 'proliferating cell nuclear antigen' ( PCNA ), distinguished by its apparent association with cell division, is defined by reaction with an antibody found in the autoimmune disease systemic(More)
Biochemical properties of the heat shock or stress proteins of mammalian cells have been investigated using two-dimensional gel electrophoresis and immunological techniques. Of the major mammalian stress proteins (Mr = 72,000, 73,000, and 90,000) and minor stress proteins (Mr = 80,000, 100,000, and 110,000), the 80- and 90-kDa proteins were found to be(More)
The strategies and methods used by the QUEST system for two-dimensional gel analysis are described, and the performance of the system is evaluated. Radiolabeled proteins, resolved on two-dimensional gels and detected using calibrated exposures to film, are quantified in units of disintegrations per minute or as a fraction of the total protein radioactivity(More)
Activated ras genes transform REF52 cells only at low frequencies and adenovirus early region 1A collaborates with ras oncogenes to convert REF52 cells to a tumorigenic phenotype. While failure to transform did not result from an absence of ras gene expression, E1A appeared to enhance expression of transfected ras genes by approximately tenfold. However,(More)
