New e-mail server for retrieving ESTs and STSs by map location
dbEST is NCBI's database of "Expressed Sequence Tags" and contains
all PUBLICLY AVAILABLE information on cDNA projects from 60 different
contributing laboratories. dbEST contains nearly 35,000 sequences from
16 different organisms and 122 different cDNA libraries. dbEST has been
operating for more than 2 years and usage has increased approximately
10-fold over the past 12 months: dbEST is now the second most frequently-
searched database at NCBI.
STSs or "Sequence Tagged Sites" are short tracts of single-copy DNA
sequences that are used as markers for the physical mapping of genomes
(Olson M, Hood L, Cantor C, Botstein D Science 245: 1434-5 (1989)).
To facilitate access to STS data in GenBank, we have created a new database,
dbSTS, and a new division of GenBank.
Now, for both STS and EST data, one may retrieve data based on
chromosome assignment or a more detailed map location.
To obtain a 'help' document describing the use of this resource:
---------------------------------------------------------------------------
mail retrieve at ncbi.nlm.nih.gov
Subject:
datalib dbest {or dbsts}
help
---------------------------------------------------------------------------
A sample query that will retrieve all ESTs (or STSs) on chromosome 7:
---------------------------------------------------------------------------
mail retrieve at ncbi.nlm.nih.gov
Subject:
datalib dbest {or dbsts}
datatype chrom
org Homo sapiens
rpt 7
---------------------------------------------------------------------------
---------------------------------------------------------------------------
All retrieve services at NCBI are being consolidated into one address,
retrieve at ncbi.nlm.nih.gov, but there is a specific syntax for retrieval by
map location as illustrated in the above example and described more fully
in the 'help' document.
In addition to providing new retrieval services for STSs and ESTs, we
have also implemented new streamlined submission procedures for these large
data sets. Please contact info at ncbi.nlm.nih.gov for more information.
