ChEBI paper

What next? What journal, what format... keep pre-submission enquiry?

Submit to another journal.  Need to finish last bit: finish last figure and add text referring to it to the 
paper.  Rework text to fit the new target journal? Chris can work on this on Monday.  Tanya to reformat references.

Protein complexes

Sandra Orchard is launching a new protein complex portal at EBI as part of InTact, the idea being that it will be the reference db for protein complexes. DB entities will be species-specific so they will still need new GO cc terms.

Meant to be complementary resource to PRO

They have a curator, and we've agreed that once she's up to speed (she started a couple of months ago) she will add cc protein complexes directly to GO using TG FF. She'll be annotating her own complex sets (human, E. coli and yeast in the first instance) but I think we should assign the GO tickets for protein complexes to her too.

They're also going to suggest some higher-structure for the GO protein complex node which currently totally flat. This will be functionally-based which I think makes sense.

Sound okay?

 Assign new complex requests to new EBI curator when she is up to speed.  Could create new complex terms in GO directly
using TG FF or create a new template (composition based) for this purpose.  Harold objects to this - for GO - define a complex
based on what it does or the process it performs. Jane: ideally define complexes functionally, not compositionally.  They are thinking of functionally-based higher order categories.

As a related issue, I notice we haven't always been adding a part_of for protein complex location. This is more important than I realised and I'm guilty of not adding it too because it can be tricky. Let's discuss

add capable _of xps for complex terms to the xp file, review in obo format, divide up depending on size of file, x-complex.obo in the extension directory

Harold also wanted to revisit the discussion on component based definitions for complexes vs function/process based. He is concerned that often the exact components are either not known completely or can vary over conditions of analysis.

We need to talk with Sandra too about the intersection between IntAct and PRO relative to the representation of protein complexes. PRO is actively curating these also. Is Sandra in touch with them. Harold is one of the curators for PRO complexes.

Interactions with CL

We need to keep this going or it will just drift further.

Interactions with CHEBI

I spoke to Janna about the lag issue we have with CHEBI releases. She's very happy to start producing a pre-release OWL version of CHEBI on a regular basis, perhaps nightly. Their OWL representation is non-standard (it has bits missing to reduce its size) but it would be straightforward to translate it into regular OWL if we need it. This can happen fairly quickly - Janna will get back to us.

They're also planning to add a lot more axioms in the fairly near future - they have some disjoints already.

protein domain specific binding

See [[1]]

Do we really want this as a template? Wouldn't this be better post-composed as an annotation extension? An InterPro id could go in column 16

Protein/glycoprotein/lipoprotein terms in ChEBI

Chris to report if there's any progress - Background here: http://wiki.geneontology.org/index.php/Ontology_meeting_2013-01-24#Protein.2Fglycoprotein.2Flipoprotein_terms_in_ChEBI

Collaboration with group at NJIT

They've produced this visualization of GO bp + xps that potentially allows us to spot problems. Wondering whether we should agree to work with them further. I'll talk everyone through this figure.
