TIGR The Institute for Genomic Research (TIGR) is a not-for-profit center dedicated to deciphering and analyzing genomes – the complexmolecular chains that constitute each organism’s unique genetic heritage.
TOUCAN TOUCAN is a workbench for regulatory sequence analysis on metazoan genomes : comparative genomics, detection of significant transcription factor binding sites, and detection of cis-regulatory modules (combinations of binding sites) in sets of coexpressed/coregulated genes.
TXTgate TXTGate is a literature index database and is part of an experimental platform to evaluate (combinations of) information extraction and indexing from a variety of biological annotation databases. It is designed towards the summarization and analysis of groups of genes based on text.


Gene Ontology & Annotation

AmiGO AmiGO is the official tool for searching and browsing the Gene Ontology database, which consists of a controlled vocabulary of terms covering biological concepts, and a large number of genes or gene products whose attributes have been annotated using GO terms.
Babelomics Babelomics is a complete suite of web tools for functional analysis of genome-scale experiments.Babelomics includes tools for functional annotation of pre-selected sets of genes, such as FatiGO+, Tissue Mining Tool and MARMITE. It also includes the FatiScan tool and an improved GSEA module to find blocks of functionally related genes.
Gene Ontology Consortium The Gene Ontology project provides a controlled vocabulary to describe gene and gene product attributes in any organism.
GeneAnnot GeneAnnot provides a revised and improved annotation of Affymetrix probe-sets from HG-U95, HG-U133 andHG-U133 Plus2.0.
GeneCards GeneCards® is an integrated database of human genes that includes automatically-mined genomic, proteomic and transcriptomic information, as well as orthologies, disease relationships, SNPs, gene expression, gene function, and service links for ordering assays and antibodies.
GeneLynx GeneLynx is a portal to a collection of hyperlinks for each gene within three different genomes (human, rat, and mouse). It is implemented as an easily extensible relational database with a straightforward user interface.
GeneTools GENETOOLS is a collection of web-based tools on top of a database that brings together information from a broad range of resources, and provides this in a manner particularly useful for genome-wide analyses.
iHOP A network of concurring genes and proteins extends through the scientific literature touching on phenotypes, pathologies and gene function.iHOP provides this network as a natural way of accessing millions of PubMed abstracts. By using genes and proteins as hyperlinks between sentences and abstracts, the information in PubMed can be converted into one navigable resource, bringing all advantages of the internet to scientific literature research.
IMAGE The I.M.A.G.E. Consortium has arrayed cDNA clones for various EST projects. A majority of the clones arrayed by I.M.A.G.E. are available royalty-free through our distributors (see the FAQ for more information), and all sequences obtained are submitted immediately to dbEST. The I.M.A.G.E. team at Lawrence Livermore National Laboratory is supported by the U.S. Department of Energy (Office of Biological and Environmental Research) and the National Institutes of Health.
KEGG KEGG: Kyoto Encyclopedia of Genes and Genomes
MGI Mouse Genome Informatics (MGI) provides integrated access to data on the genetics, genomics, and biology of the laboratory mouse.
SOURCE SOURCE is a unification tool which dynamically collects and compiles data from many scientific databases, and thereby attempts to encapsulate the genetics and molecular biology of genes from the genomes of Homo sapiens, Mus musculus, Rattus norvegicus into easy to navigate GeneReports.
UniGene Each UniGene entry is a set of transcript sequences that appear to come from the same transcription locus (gene or expressed pseudogene), together with information on protein similarities, gene expression, cDNA clone reagents, and genomic location.



Google Scholar (Beta) Google Scholar provides a simple way to broadly search for scholarly literature. From one place, you can search across many disciplines and sources: peer-reviewed papers, theses, books, abstracts and articles, from academic publishers, professional societies, preprint repositories, universities and other scholarly organizations. Google Scholar helps you identify the most relevant research across the world of scholarly research.
