EpoDB is a database of genes expressed in vertebrate red blood cells. It is
also a prototype for the creation of cell and tissue-specific databases
from multiple external sources. The information in EpoDB obtained from
GenBank, SWISS-PROT, Transfac, TRRD and GERD is curated to provide high
quality data for sequence analysis aimed at understanding gene regulation
during erythropoiesis. New protocols have been developed for data
integration and updating entries. Using a BLAST- based algorithm, we have
grouped GenBank entries representing the same gene together. This sequence
similarity protocol was also used to identify new entries to be included in
EpoDB. We have recently implemented our database in Sybase (relational
tables) in addition to SICStus Prolog to provide us with greater
flexibility in asking complex queries that utilize information from
multiple sources. New additions to the public web site
(http://www.cbil.upenn.edu/epodb) for accessing EpoDB are the ability to
retrieve groups of entries representing different variants of the same gene
and to retrieve gene expression data. The BLAST query has been enhanced by
incorporating BLASTView, an interactive and graphical display of BLAST
results. We have also enhanced the queries for retrieving sequence from
specified genes by the addition of MEME, a motif discovery tool, to the
integrated analysis tools which include CLUSTALW and TESS.
