Reactome: A Curated Pathway Database

New Software Released

Posted on April 12th, 2016, by robinhaw, under Reactome Announcement

analysis-interactors

The Reactome team has released new versions of the Analysis Service, Diagram Viewer, Pathway Browser analysis submission interface, and Search. These services, widgets and tools have been updated following user feedback with two main aims: to make them easier to use and to add extra features.

 The Analysis Service now has an option to perform an extended analysis that includes interaction data from IntAct, the EBI database of pairwise protein-protein interactions. Complementing this, the new version of the Diagram Viewer also features the overlay of analysis results when interactors are included.

In addition to the display of interactors from IntAct and PSICQUIC services, a new tool has been added to allow the user to upload and overlay custom interaction data onto diagrams. The tool supports different formats, explained in the in-line user guide. Uploaded data is kept across sessions in the same browser.

The main Search is aware of IntAct interactors, making them fully accessible via Reactome web interface queries. When a searched entity is not part of a Reactome pathway, it can still be found as an interactor of pathway entities based on the IntAct data. The search result will show the interactors with a list of all the curated entities that interact with them.

Reactome is a collaboration between groups at the Ontario Institute for Cancer Research, Cold Spring Harbor Laboratory, New York University Langone Medical Center, and The European Bioinformatics Institute.

EGFR_MIO

As part of our efforts to give our user community better experience, we have redesigned the Molecular Interaction Overlay to support quicker, easier, and more responsive access to protein-protein and protein-small molecule interaction data within the Reactome Pathway Browser.

New features and improvements include:

  • Diagram search feature includes the gene name and chemical name for interactors.
  • Interactors display name is now the gene name for proteins and the chemical name for the chemicals.
  • Tooltips are shown when hovering over the for interaction links.
  • Interactions include links to entities present in the diagram.
  • Loop-link is included when a protein/chemical interacts with itself.
  • Display option to show/hide interactors based upon a selected weighted score.
  • Crystal and chemical structures for the interactors are displayed at zoomed-in view.
  • Diagram image export for the zoomed-in view includes the protein structures in the final image.
  • Interactor file download is now available in both the Interactors toolbar and Settings panel.
