1 NCI-Nature Pathway Interaction Database (http://pid.nci.nih.gov) & the BioPAX (Biological Pathways Exchange) Ontology and Formathttp://pid.nci.nih.gov Kira Anthony Nature Publishing Group July 27, 2011

2 Pathway Interaction Database Expert curated, peer-reviewed database of signaling and regulatory pathways Assemble/visualize pathway networks by query on molecule, predefined pathway, shortest path Export predefined pathways or dynamically generated networks in BioPAX Level 2; Level 3 implementation – in progress (beta-level exports currently on FTP site) PID provides human NCI-Nature curated/Reactome/BioCarta/KEGG data in BioPAX

3 PID and BioPAX A BioPAX aim: To provide complete native representations of the source databases PID became involved in helping to determine BioPAX Levels 2 and 3 specifications General Level 3: Generics & clean-up of transcription/translation Additions/changes to BioPAX Level 2 requested/developed by PID: –Families –PTMs –State –Cleaved subunits of proteins –Evidence code ontology (ECO) –Conditions and biological processes

4 Intro to protein family spec JAM Family UniProt P57087 protein family member Level 2 relationshipXref (type=“protein family member”)  Level 3 (generic) entityReference class

5 Complex family Level 2 the protein family solution didn’t work because the member complex didn’t have a standardized name/identifier which could be cross-referenced. Level 3 the entityReference class does work.

6 PTM (known site) EQUAL 211 SequenceFeature (Level 2) replaced with entityFeature (Level 3). SEQUENCE-FEATURE-LIST (Level 2) replaced with modificationFeature, modificationType (Range: SequenceModificationVocabulary), featureLocation, featureLocationType (Level 3).

7 PTM (unknown site) phosphorylati on sequenceFeature (Level 2) replaced with entityFeature (Level 3). SEQUENCE-FEATURE-LIST (Level 2) replaced with modificationFeature, modificationType (Range: SequenceModificationVocabulary**), featureLocationType (Level 3). But no featureLocation. Level 3 **SequenceModificationVocabulary – PSI-MOD introduced

8 State (abstract) - sequenceParticipant active sequenceFeature (Level 2) replaced with entityFeature (Level 3). SEQUENCE-FEATURE-LIST (Level 2) replaced with memberFeature (Level 3) (generic).

9 State (abstract) - complex FGFR/FGF/S yndecan-2/FRS2 bp:SEQUENCE-FEATURE-LIST pid_f_203202_0X26 ; bp:FEATURE-TYPE active Level 2 resorted to comment: couldn’t put a SEQUENCE-FEATURE on a complex. Level 3 entityFeature class will work here.

10 Cleaved protein subunit FAK1 fragment 2_ protein subunit; protein id = Q05397; start = 773, stop = 1052 Resorted to a comment for subunit coordinates (Level 2); used unificationXref to the whole protein. entityFeature, fragmentFeature, featureLocation - (Utility class: 0 or more object:SequenceLocation, SequenceInterval) (Level 3).

11 Degradation class A new Degradation class: sub-class of Conversion Relevant for PID terms "degradation" and “proteasomal ubiquitin-dependent protein catabolic process”

12 Condition ACTIVATION acidic pH Minor changes: Level 2 Syntax – Name; Level 3 Syntax – standardName; Also, control interaction is separate in Level 3

13 Biological process negative regulation of muscle contraction ACTIVATION

14 Level 4 Workgroups snapshot Visualization and exchange (with SBGN) Semantic web (additional ontologies/CVs) Pathways and models (with SBO, SBML, CellML, Virtual Cell) More details: BioPAX.org

15 Additional resources BioPAX.org – community site (with specifications, documentation, L4 workgroups, BioPAX discuss listserv sign-up etc.) Next meeting: COMBINE: September 3-7, 2011, Heidelberg Pathway Commons – portal for data exported in BioPAX
