A "searchable, integrative database that provides comprehensive, user-friendly information on all annotated and predicted human genes. The knowledgebase automatically integrates gene-centric data from ~150 web sources, including genomic, transcriptomic, proteomic, genetic, clinical and functional information."
BLAST (from NCBI) finds regions of local similarity between sequences. It compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches.
The European Nucleotide Archive (ENA) provides a comprehensive record of the world’s nucleotide sequencing information, covering raw sequencing data, sequence assembly information and functional annotation.
UniProtKB/Swiss-Prot is the manually annotated and reviewed section of the UniProt Knowledgebase (UniProtKB).
It is a high quality annotated and non-redundant protein sequence database, which brings together experimental results, computed features and scientific conclusions.
DDBJ Center collects nucleotide sequence data as a member of INSDC (International Nucleotide Sequence Database Collaboration) and provides freely available nucleotide sequence data and supercomputer system, to support research activities in life science.
NCBI's mission is to develop new information technologies to aid in the understanding of fundamental molecular and genetic processes that control health and disease
The European Bioinformatics Institute (EBI) is a centre for research and services in bioinformatics, and is part of European Molecular Biology Laboratory (EMBL). Its website provides analysis tools and several databases of biological data, including nucleic acid, protein sequences, and macromolecular structures. It also provides information on current research.
The Arabidopsis Information Resource (TAIR) maintains a database of genetic and molecular biology data for the model higher plant Arabidopsis thaliana .
