Database Description

InterPro, an integrated documentation resource of protein families, domains and functional sites, was created in 1999 to amalgamate the major protein signature databases into one comprehensive resource. PROSITE, Pfam, PRINTS, ProDom, SMART, TIGRFAMs, PIR SuperFamily and, the structure-based SUPERFAMILY have been manually integrated and are available in InterPro for text- and sequence-based searching. CATH and PANTHER HMMs will soon be integrated. The results are provided in a single, comprehensive format, with links to the original data sources, as well as specialised functional databases. The latest release of InterPro contains over 10,000 entries, with 78% coverage of all proteins in UniProt. Each entry has annotation provided in the name, GO mapping and abstract fields, and all matches against the Swiss-Prot and TrEMBL components of UniProt are precomputed and available for viewing in different formats. Protein 3D structural information is integrated from MSD, CATH and SCOP, and this data is available in the match views to provide an at a glance comparison of sequence and structural domains. The database is available via a webserver (http://www.ebi.ac.uk/interpro) and anonymous FTP (ftp://ftp.ebi.ac.uk/pub/databases/interpro). InterProScan provides a sequence search package that can be used via a web interface or can be installed locally for bulk searches.

Recent Developments

New features of the database include improved match views and a taxonomy servlet. The match views now include both extended and compact views that can be ordered by protein accession number, name, taxonomy or by proteins of known structure. The InterPro Domain Architectures view is a graphical representation of protein domain architecture, where the domain architecture of a protein sequence is displayed as a series of non-overlapping domains. This provides a means of viewing and displaying protein domain compositions. The taxonomic range of proteins matching each InterPro entry is displayed in a new field. The number of proteins matching each taxonomic group links to the graphical view of that subset of proteins. The first HMMs from the CATH database, which bases its entries on structural superfamilies from CATH, have been integrated, and PANTHER is the next database awaiting integration.
