[Caution] DDBJ terminated accepting new submission of MGA data.
In order to accept a large scale of sequence data that provide useful information for annotation of genome assemblies/sequences, the International Nucleotide Sequence Database Collaboration (INSDC; DDBJ/EMBL-Bank/GenBank) have created a new category. The name of this new category is Mass sequence for Genome Annotation (MGA). The definition of MGA data is the following.。
Sample flat file
MGA data are published a resource as a unit. The data consist of "Master record" and "Variable record" for a resource.
Common parts of information such as submitters, keywords (MGA and others), references, comments and so on. Master record is provided for every resource unit.

Contact:Hanako Mishima National Institute of Genetics, DNA Data Bank of Japan; Yata 1111, Mishima, Shizuoka 411-8540, Japan REFERENCE 2 AUTHORS Mishima,H., Shizuoka,T. and Fuji,I TITLE The gene expression analysis of short transcripts tags JOURNAL Unpublished (2010) COMMENT The CAGE (cap analysis gene expression) is based on preparation and sequencing of concatamers of DNA tags deriving from the initial 20/21 nucleotides from 5' end mRNAs. Full-length cDNAs were at first selected with the Cap-Trapper method. Then, a specific linker (Linker1, some linker contain 5 bp sequences that have 15 variations for each rna sample) containing the ClassIIs restriction enzyme site MmeI was then ligated to the single-strand cDNA and then the second strand of cDNA synthesized.
