Nucleotide Sequence Submission
It is now the usual practice for authors to acquire accession numbers to their sequences when they submit articles to journals. DDBJ is here for the author and the journal. DDBJ is also ready to assign accession numbers to sequences even if any publication is neither accompanied nor expected. The data archived in the International Nucleotide Sequence Databases by DDBJ will be diffused to the public by DDBJ, EMBL-Bank/EBI and GenBank/NCBI, and other data distributors. Thus, DDBJ is here for users as well.
If you are to submit not only nucleotide sequence data but also raw outputs from sequencers, please read DDBJ Trace Archive (DTA) and DDBJ Read Archive (DRA)
It would make your submission quick and clean, if you could read the following document in advance:
Workflow of the data submission to DDBJ
1 Data Submission
- (A) SAKURA via a WWW server
- SAKURA is a nucleotide sequence data submission system. DDBJ generally recommends you to use SAKURA.
Please have a neat list of the following 5 types of data:
- Contact person
- Date of data release to the public
- Publication
- Scientific name(s) and the relevant information on the source of your sequence(s)
- Sequence data
- (B) Mass Submission System(MSS)
- We recommend the use of the Mass Submission System (MSS) if: (1) the submission consists of large number of sequences (entries), or (2) the submission involves long nucleotide sequences which result in a complex submission containing many features as in the case of genome data, or (3) the submission cannot be handled by SAKURA. Please go to the Mass Submission System for details.
- (C)Sequin
- Although DDBJ strongly recommends the use of (A) or (B), DDBJ can accept your submission using Sequin.
Sequin is stand-alone software to make files for data submission.
Please refer here for details.
2 Annotation
We annotate in accordance with our rules and the international rules agreed upon by the DDBJ/EMBL/GenBank consortium. In the annotation process, we may contact the Contact Person to make inquiry about the data.
3 Assignment and Notification of Accession Number
We e-mail an accession number (unique number assigned by the International Nucleotide Sequence Database Collaboration) to the Contact Person whose E-mail address is entered in the "Contact person E-mail address" field on SAKURA or Contact window on Sequin. This notification is normally sent within five business days after receipt of the data. Please contact sakura-admin@ddbj.nig.ac.jp if you do not hear from us within this time period.
4 Report of Data Releasing
We notify data release to the Contact Person by E-mail or FAX. Once the data are released, please confirm the data by one of the retrieval tools accessible from the DDBJ homepage (e.g., getentry).
If you would like to update your data, please send a request mail to 
with the necessary information.
Please refer to Updates/Correction (after getting your accession number) for details.
