INTRODUCTION

The Cellular Network Knowledge Base (CNKB) maintains the B-cell Interactome and stores protein-protein and protein-dna interactions from several public databases. It stores sequence info, interaction type, GO annotation, cellular and molecular phenotype context for the interaction, algorithm or experimental procedure for inferring the interaction, and homology relationships across multiple species. One CNKB table is available for querying via a geWorkbench plugin and for visualizing interactions in geWorkbench Cytoscape module, but the number of tables accessed by geWorkbench needs to be extended in order to provide more information to the user.

REQUIREMENTS

  • make the database schema compatible with the BioPAX ontology requirements
    • import data in BioPAX markup
    • export data in BioPAX markup
  • associate all pathologies referenced in the database with their appropriate histology ICD9/ICD10 codes
  • the cellular component of a particular interaction should be linked to one or more Gene Ontology terms, parent & child nodes
  • each interaction should be associated with one or more Gene Ontology molecular functions
  • store microarray annotation data for widely-used Illumina chip platforms
  • store runtime information (command-line string) for programs such as ARACNE or MINDY
