This resource provides information on the status of the Saccharomyces
cerevisiae genome. It includes information on the genomic features and GO
annotations. All the data displayed on this page are available in one
or more files (SGD_features.tab, gene_associations.sgd,
go_slim_mapping.tab) at SGD's FTP site. The Advanced
Search tool can also be used to retrieve chromosomal features that match specific criteria.
A pie chart showing the breakdown of the number of Verified, Uncharacterized and
Dubious protein coding ORFs in the S. cerevisiae genome. ORFs are classified
as "Verified",
"Uncharacterized", or "Dubious" by SGD according to
the degree of certainty that each ORF actually encodes a protein.
The Genome Inventory table provides a count of each feature type in
the genome and in each chromosome. Definitions for each feature type
can be found in the Glossary. In addition, the table also lists
the size of the genome and of each chromosome. This
table is updated everyday. Clicking on any of the feature types
will provide a complete list of that feature type along with
their coordinates and other details like gene names and description.
This summary table provides the current total number of S. cerevisiae
gene products (protein and RNA gene products) that have been annotated
to one or more terms in each GO aspect (Biological Process, Molecular
Function and Cellular Component). Please note that these counts do not include the GO
annotations made for ORFs classified as "Dubious", or for features of
type "Pseudogene", "Not in S288C" or "Not physically mapped". Also
note that the number of annotations displayed in the "Total Number of
Annotations" column does not include annotations to the three terms
representing lack of knowledge at this time, i.e. "molecular_function
unknown", "biological_process unknown", or "cellular_component
unknown". The gene_associations file available at SGD's FTP site
provides the GO annotations for S. cerevisiae gene products.
This section provides three bar graphs that represent the GO
annotation status of the entire genome using the yeast GO-Slim (a
high-level subset of Gene Ontology terms that allows grouping of genes
into broad categories such as "DNA replication", "protein kinase
activity", or "nucleus") tailored to yeast biology. GO-Slim terms
representing broad categories from a single aspect are listed for each
graph, along with the percentage of S. cerevisiae gene products
annotated to a specific term that maps up the ontology to the GO-Slim
term. The complete
mapping approach, which maps features to all available GO Slim terms is used to generate the bar graphs. Only the distribution of "known" Molecular Functions, Biological
Processes, and Cellular Components are included in these graphs;
annotations to "unknown" are excluded.
More information on GO and GO-Slim can be found in SGD's GO help
page. To obtain the GO data summarized in these graphs, please contact
SGD curators. This data is also available in the go_slim_mapping.tab file, on
SGD's
FTP site .
The bar graphs are generated once a day.
