DDBJ; DNA Data Bank of Japan is the sole nucleotide sequence data bank
in Asia, which is officially certified to collect nucleotide sequences
from researchers and to issue the internationally recognized accession number to data submitters. DDBJ exchange the collected data with EMBL-Bank/EBI; European Bioinformatics Institute and GenBank/NCBI; National Center for Biotechnology Information
on a daily basis, the three data banks share virtually the same data at
any given time. The virtually unified database is called "INSD; International Nucleotide Sequence Database". DDBJ
collects sequence data mainly from Japanese researchers, but of course
accepts data and issue the accession number to researchers in any other
countries.
Nucleotide database can be searched by:
Getentry: Data retrieval by accession numbers, etc.
ARSA: All-round Retrieval of Sequence and Annotation.
TXSearch: Retrieval of unified taxonomy databas.
BLAST: Homology Search.
