TRANSPATH

TRANSPATH

 

 
TRANSPATH® is a database of mammalian signal transduction and metabolic pathways. As one of the earliest pathway databases ever created, it has grown since to the remarkable volume of more than 458,000 manually curated reactions. One of the largest pathway databases available, optimally suited for geneXplain’s proprietary Upstream Analysis
 
Its contents can be used for pathway analysis with the geneXplain platform, requiring separate licensing (see below).

TRANSPATH organizes the information about genes/molecules and reactions according to multiple hierarchies. Its sophisticated structure makes it one of the scientifically best conceptualized pathway resources, suitable for multi-purpose uses. It is complemented by one of the richest corpora of pathway data available among all public domain and commercial sources, all manually curated by experts.

Individual reactions are documented with all experimental details, in a strictly mechanistic way that includes all reaction partners and the taxonomic origin of each molecule as reported in the published experiment (“molecular evidence level”). All evidences for a certain pathway step are accumulated to provide a more comprehensive and complete picture (“pathway step level”). On top, a semantic view is provided, which focuses on the key components only and omits mechanistic details as well as small abundant molecules (“semantic projection”).

Complete networks and pathways are built from molecules and their reactions. To consider the heterogeneity of information given in the original publications, TRANSPATH transparently but precisely differentiates protein molecules according to:

    • their relatedness within one genome
      Information can be specifically retrieved regarding

      • (a) specific individual proteins,
      • (b) all products of a certain gene (isoforms),
      • (c) different family relation levels (e.g., paralogs);

 

    • their relatedness between different genomes (orthology)

 

  • their association and modification status
    • (a) protein complexes are specified with their exact composition;
    • (b) post-translational modifications are given with their exact positions in the protein.

Current TRANSPATH® release

TRANSPATH® release 2021.2

The TRANSPATH® database on mammalian signal transduction and metabolic pathways contains these new data features:

  • BIOPLEX 1 and 3 interactome data imported

Integration of BIOPLEX human interaction data from release 1 and 3 resulted in 131,566 new and 60,151 reactions updated with additional experimental evidence.

    • Human Reference Protein Interactome (HuRI) integrated

    45,468 new reactions were imported from the HuRI mapping project. In addition, 6,371 existing reactions were updated with experimental evidence from HuRI.

    • Increase in number of reactions

    29,662 new binding reactions between proteins in human have been added, among them e.g. from interactome in mitochondria and the bromodomain protein interactome.

    • Update of links to pathway databases

    Links from genes/proteins to the pathway databases Reactome (version 77) and Wikipathways (20210610) have been updated.
