| Entry | The KEGG GENES database contains protein-coding genes (designated as CDS) and RNA genes (tRNA, rRNA or ncRNA) in KEGG organisms (complete genomes) and viruse, which are taken from NCBI RefSeq and GenBank, as well as functionally characterized proteins manually created from published literature. Each entry is identified by the combination of the organism code (or vg for viruses and ag for addendum proteins) and the entry name. |
|---|---|
| Symbol | Gene symbols where the primary symbol shown first may be used as an alternative identifier, although it may not be unique. |
| Name | Gene product name given by the original database. The annotation given by KEGG is shown in the "KO" subfield. Note that the original annotaion is not modified even if it contradicts to the KEGG annotation. |
| Organism | KEGG organism name. |
| Pathway | KEGG pathways to which the gene has been mapped through the KO system, suggesting functional roles of the gene product in the context of molecular networks. By clicking on the link, the rectangular object of this gene product is marked red in the pathway map. |
| Module | KEGG modules to which the gene set containing this gene has been validated through the KO system. By clicking on the link, the rectangular object of this gene product is marked red in the module diagram. |
| Network | KEGG network variation maps (nt entries) and network elements (N entries) that contain this gene or its variant. By clicking on the nt link, the gene name is framed red in the variation diagram. |
| Disease | Known association to diseases as stored in the KEGG DISEASE database. |
| Drug target | Known drugs that target this gene product as stored in the KEGG DRUG database. |
| Brite | Hierarchical classification of gene functions according to the KO system, as well as protein families and other classifications in the BRITE database. |
| SSDB | SSDB contains computational results of selected pairwise genome comparisons in KEGG organisms using the SSEARCH program. The Ortholog link generates possible orthologs based on the information about best hits and the Paralog link generates possible paralogs. The GFIT link displays a read-only version of the KEGG annotation tool GFIT. |
| Motif | Precomputed Pfam domains. |
| Other DBs | Links to the outside database resources. |
| LinkDB | 'All DBs' button in this field retrieves all available links to related database entries in the LinkDB system. At GenomeNet this field does not appear; instead a list of actual links is displayed on the right. |
| Structure | Links to the 3D structure data in the PDB database. |
| Position | The chromosomal position of the gene and, when all the nucleotide positions are known, the link to the KEGG genome map browser. |
| AA seq | The number of amino acids and the sequence data. The AA seq link generates the sequence data in the FASTA format. The DB search link can be used for sequence similarity search by BLAST or FASTA against various databases. |
| NT seq | The number of nucleotides and the sequence data. The NT seq link generates the sequence data of the coding region and flanking regions in the FASTA format. |
