The databases Swiss-Prot, TrEMBL, PROSITE, PRINTS, Pfam, and ProDom joined forces to launch an Integrated Documentation Resource of Protein Families, Domains and Functional Sites, abbreviated InterPro. SMART, TIGRFAMs, PIR SuperFamilies and more recently SUPERFAMILY joined InterPro. A detailed description of the project can be found in the user manual.

Changes since last release

The protein matches have been updated according to the latest updates of Swiss-Prot and TrEMBL. New methods from SUPERFAMILY, TIGRFAMs, Pfam and PROSITE have been integrated. In the match.xml file element, 'match', now contains new attribute 'score', which corresponds to the score given by InterProScan. Also, every match element now contains start and end positions. In the cases where there is no position information (manual assignment by curators) both values equal to zero.

Links to COMe, the bioinorganic motif database and MEROPS, a database of peptidases and protein inhibitors have been included.

COMe is an attempt to classify metalloproteins and some other complex proteins using the concept of bioinorganic motif. A bioinorganic motif (BIM) may be defined as a common structural feature of a class of functionally related, but not necessarily homologous, proteins, that includes the metal atom(s) and first coordination shell ligands.

MEROPS classifies peptidase inhibitors and peptidases. Only links to the peptidases are available in this release.

InterProScan has been updated to include new member database signatures and SUPERFAMILY HMMs and a new version implemented, which has increases functionality and new capabilities. In this release upto a maximum of 10 protein sequences or 1 nucleic acid coding sequence sequence can be submitted. For the analysis of nucleic acid sequences the minimum open reading frame size can be selected (range 20 to 150).

Contents of current release

InterPro release 7.1 contains 10403 entries, representing 2239 domains, 7901 families, 197 repeats, 26 active sites, 20 binding sites and 20 post translational modifications. Overall, there are 5211420 InterPro hits from 1152185 Swiss-Prot + TrEMBL protein sequences. A complete list is available from the ftp site.

Forthcoming changes

The next release of InterPro will be release 7.2 scheduled for March 2004. This will include new data from the member databases. It will also include further improvements to the taxonomy servlet, and incorporation of MEROPS database peptidase inhibitor classification.
