About this newsletter:

This is the May 2007 issue of the quarterly SGD newsletter. The goal of this newsletter is to inform our users about new features in SGD and to foster communication within the yeast community. You can also subscribe to SGD's RSS feed to receive updates on SGD news -

Community Wiki Available

In order to facilitate sharing of information about S. cerevisiae genes, gene products, and resources within the yeast community, SGD now includes a Community Wiki. Like the popular Wikipedia, the SGD Community Wiki is a set of web pages that allow users to easily add and edit information. This Community Wiki has been pre-loaded with basic locus information from SGD as well as user annotations previously submitted through the Community Annotation pages. We invite the research community to further develop and enhance the information on the wiki pages. For example, the Wiki would be the ideal place to share comments on particular deletion strains or record differences in mutant phenotypes in different strain backgrounds. Links are available in the "Additional Information" section and from the "Literature" pull-down of each Locus Summary page as well as on the Community Info contents page.

Nucleotide-level Variation Among Commonly Used Yeast Strains

Schacherer et al. identify SNPs between S288c and seven commonly used lab strains; these data are available on the SGD FTP site and can be searched and viewed online via the Yeast SNPs Browser available at Princeton University.

New or Updated Summary Paragraphs

Summary Paragraphs summarize published biological information for a gene/feature, and are designed to familiarize both yeast and non-yeast researchers with the general facts and important subtleties regarding a locus. During the last quarter (February - April 2007), new summary paragraphs for the following 695 features have been added to their respective Locus Summary pages.

List of Summary Paragraphs Added During the Last Quarter
STE20/YHL007C 85 RPL genes 56 RPS genes 7 RPP genes 50 Retrotransposons
382 Long Terminal Repeats 89 Transposable Element Genes

GO Annotations from GOA-UniProt Added

SGD has incorporated manual GO annotations for S. cerevisiae proteins from the GO Annotation (GOA) project at EBI. These annotations can be identified at SGD by the source, e.g., 'UniProt', displayed on the 'Assigned By' column of the GO evidence and references page. The GO evidence and references page can be accessed by clicking on the 'Gene Ontology' tab from any Locus Summary page (e.g., please see Gene Ontology evidence and references page for RSC6). The gene_associations.sgd file, which provides a complete set of manual GO annotations for S. cerevisiae, now includes these annotations from the GOA UniProt file.

5' UTR introns Added

Locus Summary page annotation has now been expanded to include introns located in the 5'-untranslated regions (5' UTRs) of primary transcripts. The Advanced Search can be used to obtain a complete list of genes with 5' UTR introns. We thank the many researchers who generated these data and reviewed our incorporation of it, including Manny Ares, Paul Cliften, Zhihong Zhang, Kara Juneau, and Takashi Ito.

Sequence and Annotation Updates

As new data become available, SGD curators update the systematic sequence and its annotation. Information regarding sequence and annotation changes can be found via the Summary of Chromosome Sequence and Annotation Updates and in the "Locus History" pages of affected features. Files on the SGD FTP site are updated weekly. During the last quarter (February - April 2007), sequence and annotation changes were made affecting 37 features and 11 new features were added.
