13.09.2014 Master title • Molecular Interactions – the IntAct Database • Sandra Orchard • EMBL-EBI 5 EBI is an Outstation of the European Molecular Biology Laboratory.
IntAct goals & achievements • Publicly available repository of molecular interactions (mainly PPIs) - >275K binary interactions taken from >5,000 publications (September 2011) • Data is standards-compliant and available via our website, for download at our ftp site or via PSICQUIC • Provide open-access versions of the software to allow installation of local IntAct nodes. http://www.ebi.ac.uk/intact ftp://ftp.ebi.ac.uk/pub/databases/intact www.ebi.ac.uk/Tools/webservices/psicquic/view/main.xhtml

Interacting domains Overlay of Ranges on sequence: Data model • Support for detailed featuresi.e. definition of interacting interface
How to deal with Complexes • Some experimental protocol do generate complex data: • Eg. Tandem affinity purification (TAP) • One may want to convert these complexes into sets of binary interactions, 2 algorithms are available:
