About Xpro:
Xpro
is a relational database that contains all the eukaryotic
protein-encoding DNA sequences in
GenBank. It provides detailed and comprehensive features about both the
intron containing and the intron-less genes.
In addition to the information found in the GenBank records,
which includes properties such as sequence, position, length and
description about introns, exons and protein coding regions, Xpro
provides annotations on the splice sites motifs and intron phases.
Furthermore, Xpro validates intron positions using alignment information
between the records sequence and EST sequences found in dbEST. The
entries in the XPro are also cross-referenced to
SWISS-PROT/TrEMBL and
Pfam
databases.
The current release of
Xpro (v.1.2, Jan 2004) is
MySQL (v 3.23.39)
relational database and contains information up to
date with GenBank release 139.
For viewing the data content in the current version of Xpro, kindly
refer to the following 'Statistics' link
http://origin.bic.nus.edu.sg/xpro/statistics.html.
Note:
Xpro focuses only on the CDS region and does not contain details about
introns, exons in the 5' and the 3' UTR regions of the eukaryotic genes.
Search parameters :
The database can be searched using any of the
following details<
- GenBank locus name (e.g. AL91370,
H006101S22)
- Nucleotide accession or version number
(e.g. AF016365.1)
- Valid GenBank ID (e.g. 2873347)
- Protein accession number (e.g.
CAD24437.1)
- Keywords in the Genbank Definition
(e.g. yeast, gdnf, etc)
- SWISS-PROT/TrEMBL accession numbers
-
Pfam accession numbers
The database also can be searched against
a nucleotide or protein sequence for homologues using the BLAST
