UNLABELLED: ProViz is a tool for the visualization of protein-protein interaction networks, developed by the IntAct European project. It provides facilities for navigating in large graphs and exploring biologically relevant features, and adopts emerging standards such as GO and PSI-MI. AVAILABILITY: ProViz is available under the GPL and may be freely downloaded. Source code and binaries are available at http://cbi.labri.fr/eng/proviz.htm CONTACT: [email protected]

UNLABELLED: AliasServer provides services that facilitate the assembly of data or datasets that make use of different identifiers for refering to the same protein. This resource relies on a database which contains, for a given organism, a non-redundant list of protein sequences associated with a set of aliases. AVAILABILITY: AliasServer is available as an interactive Web server at http://cbi.labri.fr/outils/alias/ and as a web service using a SOAP interface. The complete tool, including sources and data, is available for local installations upon request. SUPPLEMENTARY INFORMATION: Technical documentation is available at http://cbi.labri.fr/outils/alias/asdoc.pdf

Abstract Summary: IPPRED is a web based server to infer protein–protein interactions through homology search between candidate proteins and those described as interacting. This simple inference allows to propose or to validate potential interactions. Availability: IPPRED is freely available at http://cbi.labri.fr/outils/ippred/.
