Creation of GO annotations using phylogenetic inference
- We have now annotated, in total, gene families covering approximately 7200 human genes. This represents about 36% of all protein-coding genes. As of this time last year, we had covered only 15% of human genes, so we covered an additional 21% this year (nearly meeting our original goal for year 4 of 24%, which assumed substantially greater resource allocation).
- Of these 7200 human genes that could have potentially received additional GO annotations, the project added new annotations for about 6000 human genes (over 80%). A total of 25,000 annotations were added for these human genes (12,000 biological process, 7,000 molecular function and 6,000 cellular component annotations). This project is thus making a large impact on the computational representation of human gene function.
- The project also added new annotations for an additional ~300,000 genes across 104 other genomes.
- Other statistics: 2300 families have now been curated. This has resulted in the annotation of 5300 internal tree nodes, comprising 2400 molecular function annotations, 3200 biological process annotations and 2600 cellular component annotations. These annotations were propagated within the tree to annotate the 300,00 genes listed above, yielding a total of 565000 biological process annotations, 430,000 molecular function annotations and 360,000 cellular component annotations.
- Updated the phylogenetic trees. All gene trees were updated using the May 2015 release of the UniProt Reference Proteomes.
- PAINT: A major refactoring of PAINT was carried out to utilize the touchup logic server. This is current in an early release and being tested by the curators. In addition, a number of user features and more subtle bugs were fixed. For example: a bug in Java 1.7 sorting was detected when we were increasing the speed of loading the ontology; Version, date and user are now recorded in the GAF, log file and the title bar; considerable time was spent in making PAINT more clever in terms of ID resolution to ensure that no new gene products are introduced into the GO database that in fact are already present under a different ID.
- PANTHER release wrangling: Whenever there is a new release of PANTHER (this year produced v10) a number of steps must be taken to incorporate the new release everywhere it is used. New families may be added, previous families may disappear, and annotated nodes may move from one family to another. Scripts are required to cope with all of these changes and these have been written. The “salvage” script removes nodes from the old family GAF file and adds these to the new family GAF file, it also copies over any curator added notes and commits the modified GAFs to the GO repository. In addition, before running either PAINT or Touchup, a check must be carried out to ensure that all the taxa included in this PANTHER release are accounted for by the current taxon checker. And finally, to load the families into AmiGO, the tree files must be corrected to standard newick format (.nhx suffix) and converted into JSON objects. Similarly the default database names used may change between PANTHER releases (e.g. WormBase changed to WB in PANTHER v10).
Plans for coming year (Software)
- Develop Selenium/behave tests
- Develop training material for PAINT
- Integrate JS-PAINT with Noctua and TermGenie
- Ensure touchup is run regularly as part of the continuous integration pipeline
