5. + Plasmodium falciparum | Homo sapiens The species in the interaction are recorded... by entering two taxon IDs in the Taxon column: First taxon ID: species encoding the gene product First taxon ID: other species in the interaction. Why not just plasma membrane? GP of one organism in CC of another

6. + A duplicate cell component branch is growing under host-cell Why? Keeps annotations of gene products located in CCs of host organism separate from regular GO CC annotations.

7. + A duplicate cell component branch is growing under host-cell Many terms duplicate the regular cell component hierarchy. THIS IS NOT SUSTAINABLE Some terms refer to components that are formed from the interaction of 2 organisms. Add new parent class for these: multi-organism cell component

8. + Proposed solution Plasmodium falciparum parasite_of Homo sapiens located_in GO:0005886 plasma membrane + annotation extension: part_of Homo sapiens

9. + Proposed solution Plasmodium falciparum parasite_of Homo sapiens located_in GO:0005886 plasma membrane When used, replaces part_of as default GP to CC relation in GPAD Tools used for grouping annotations need to group these annotations separately. Precedent: NOT New qualifier / GP to CC relation: located_in + annotation extension: part_of Homo sapiens

10. + Proposed solution Plasmodium falciparum parasite_of Homo sapiens located_in GO:0005886 plasma membrane New qualifier / GP to CC relation: located_in + annotation extension: part_of Homo sapiens Replace host CC term with regular one, recording the taxon of the organism it is part of in the annotation extension.

11. + Proposed solution Plasmodium falciparum parasite_of Homo sapiens located_in GO:0005886 plasma membrane Taxon extension – using standard relations between organisms : host_of, symbiont_of, parasite_of vector_for… Relations defined with population and community ontology (PCO) + annotation extension: part_of Homo sapiens

12. + Proposed solution – retrofit when host not recorded Plasmodium falciparum symbiont_of host organism * located_in GO:0005886 plasma membrane + annotation extension: part_of host organism * * Generic host organism class from PCO

16. + What does annotation mean? Too strong: All instances of the RIF gene product are located in some plasma membrane that is part of some Homo sapiens. All instances of the ICAM-1 gene product are involved in some HRV3 virion attachment to (human) host cell.

17. + Capabilities are not necessarily realised All sperm capable_of (some) fertilization But not all sperm do. In fact most do not. All ICAM-1 gene product capable_of_part_of some ‘virion attachment to host cell’ But most don’t.

18. + LEGO-ish class level formalisation of ‘lego’ brick Gask3 SubClassOf: capable_of some ('protein kinase activity' that (part_of some 'canonical wnt signalling’) and (occurs_in some cytosol)) protein kinase activity canonical Wnt signaling P Gask3 b cytosol

19. + The same pattern works for three separate annotations Gask3 SubClassof: capable_of some 'protein kinase activity’ capable_of some('molecular_function' that (part_of some 'canonical wnt signalling')) capable_of some ('molecular_function' that (occurs_in some cytosol)) protein kinase activity canonical Wnt signaling P Gask3 b cytosol

20. + Using this pattern for localisation to CC of an interacting organism RIF subClassOf: capable_of some ( 'molecular function' that occurs_in_location some ( 'plasma membrane' that part_of some ( 'Homo sapiens' that host_of some 'Plasmodium falciparum 3D7’ ) occurs_in_location = more general version of occurs_in that entails location rather than parthod

27. + Possible Solutions: Parallel translations? Same basic pattern used in each case Lego bricks capture a set of related findings in a single paper Class level assertion makes sense for this Lego construction captures a model of how these fit together under some circumstances… Change LEGO pattern CC & GP both become individuals
