- The International Nucleotide Sequence Databases (INSD) discussed the issue
of receiving and releasing huge amounts of transcript sequence, each of
which is a 5' end short-length transcript approximately 20 bp in length.
They are produced by the CAGE (Cap Analysis Genome Expression) method and
thus called the CAGE sequences. INSD then agreed that the sequences be
submitted and released as a new category, MGA (Mass sequence for Genome
Annotation), because the sequences are of new type and not fit to any of
the extant divisions or categories.
-
Definition of MGA
MGA is defined as those sequences which are produced
in large quantity in view of genome annotation.

-
- The first set of MGA was released on January 24, 2005. The MGA data for
mouse were submitted from Dr. Yoshihide Hayashizaki and his colleagues of
the Genome Sciences Center at RIKEN. The total number of sequence entries
this time is 383,264. The MGA data can be downloaded at the ftp site,
-
- ftp://ftp.ddbj.nig.ac.jp/ddbj_database/mga/ (MGA directory)
- ftp://ftp.ddbj.nig.ac.jp/ddbj_database/mga/project_index.html (Project index)
-
- Most of the present MGA sequences are associated with the gene expression
data which have already been released at
CIBEX, one of the
international gene expression databases, operated at the Center for
Information Biology and DNA Data Bank of Japan.
