Descriptions: GoPubMed is an innovative, powerful search tool that combines the MeSH (Medical Subject Headings) and GO (Gene Ontology) terminologies to optimize the effectiveness of queries to PubMed- for everyone, but for molecular biologists in particular. Searching elicits results presented very quickly (maximum display: the most recent 1,000 citations), along with a sidebar presenting the full results in categorized, hierarchical groups of terms that help the user to focus in further- the producers of this search engine refer to it as a "knowledge-based semantic search." There are many more features to this search tool than can be described here.

Gene Ontology


Provider: Gene Ontology Project
Contents: , , ,
Access Level: ,
Descriptions: "The Gene Ontology project is a major bioinformatics initiative with the aim of standardizing the representation of gene and gene product attributes across species and databases. The project provides a controlled vocabulary of terms for describing gene product characteristics and gene product annotation data from GO Consortium members, as well as tools to access and process this data."  The Ontologies describe three aspects of molecular biology- biological processes, cellular components, and molecular functions. Gene Ontology's collected tools list includes hundreds from all over the world: specialized browsers, search engines, statistical analysis and visualization tools, and many other kinds. This project began as a collaboration between three model organism databases, FlyBase (Drosophila), the Saccharomyces Genome Database  and the Mouse Genome Database  in 1998. Since then, the GO Consortium has grown to include many other databases, including several of the world's major repositories for plant, animal and microbial genomes. See the GO Consortium page for a full list of member organizations.
