Old Phenotype2GO pipeline (Sanger and Caltech)
- The old Sanger script that generates the gene_association file (from Igor's work in January 2009) was changed. Instead of an exclusion list and 'include list' that comprises papers (mostly large scale genome-wide studies) is provided to the script. This list is curator approved and explicitly agreed upon for the propagation of GO terms to genes based on their RNAi phenotypes.
- A new script is used, to use it invoke the script with the -includelist option, e.g.: Run parse_go_terms_new.pl -o gene_association.wb -rnai -include includelist.txt (this example only parses RNAi experiments, to generate full file, you should also give '-gene -var' options as before).
- If you invoke it with '-acefile <filename>' option, the script will also generate Gene-GO_term connections derived from phenotypes. This is currently done by the phenotype procedure of the inherit_GO_terms.pl script.
- The old script: inherit_GO_terms.pl does not consult any exclusion/inclusion files. To alter Sanger's version of parse_go_terms_new.pl, a patch file was provided.
- Current status:From Igor's e-mail, March 2009: I don't think the phenotype option of the inherit_go_terms script has been disabled. The script should be run without the '-variation' option, but the gene_association file still has those. Try this:
grep -i wbpheno gene_association.WS200.wb.ce |grep -v RNAi This is now resolved.

Software Development: Tools and Scripts
From Chris Mungall, 8/19/2011:
The taxon checks are run weekly, and the reports deposited here:
Note that this service will be subsumed into a more comprehensive annotation QC service (apologies if you weren't at the USC meeting, where this was demoed). This is, in general, the plan for many of the ad-hoc scripts and cron reports we perform now. I will send an email to the GOC list next week describing the roll-out process for this.
For the QC checks, the idea is to push the checking as far upstream as possible. A weekly report is too reactive. This could be done at the time of submission. Even better, the annotation tool could use the central web service at the time of annotation.

Cellular Component Annotations
If a protein contains a transmembrane domain, but expression experiments are not at sufficient resolution to show membrane localization, what annotation should we make?
WormBase use of Column 16
Column 16 refers to a column in the Gene Ontology's (GO) tab-delimited gene association file (gaf) that WormBase submits to the GO consortium on a regular basis.
Column 16 has been referred to as the Annotation Extension column in that it provides a placeholder for curation details that cannot be captured by a GO term alone, for example the substrate upon which an enzyme acts.
A number of different types of information could conceivably be entered into Column 16. The list below begins to document the potential use of Column 16 by WormBase curators with any additional information or questions that have arisen during the course of curation.
In the GAF, there will be an explicit relationship between the entity in Column 16 and the GO term. The annotation extension relations are viewable here:
Column 16 curation at WormBase is just beginning and will likely be fleshed out more fully over the next few months.
In the Ontology Annotator, Column 16 data is being entered into the 'Xref to' field in the following format: Column 16: Xref ID
Biological Process Examples:
Example 1: sup-26 is annotated to GO:0017148, negative regulation of translation. The entry in Column 16 is the target of that regulation, tra-2.
In OA entry: Column 16: WB:WBGene00006605
def: "Identifies a gene or gene product affected by a regulation BP or regulator MF." [GOC:mah]
comment: probably want to add one or two new subtypes that capture something about directness
domain: GO:0065007 ! biological regulation
range: TEMP:0000003 ! gene or gene product
Example: sup-12 mutations affect splicing of unc-60 transcripts.
Example 1: lys-7 is required for defense response to Cryptococcus neoformans
In OA entry: Column 16: NCBI:192011 (a taxon ID)
Response to Terms
Example 1: daf-2 is shown to be involved in response to oxidative stress by treating animals with paraquat. WBPaper00005488
In OA entry: annotate to 'response to oxidative stress' using CHEBI:34905
Cell Fate Specification
Example 1: egl-38 is found to be required for cell fate specification in the male tail. WBPaper00002924
Could add a number of Anatomy Terms to Column 16 (not done yet).
Regulation of Protein Localization
Example 1: hmp-1 and jac-1;hmp-1 double mutants are shown to affect the distribution of HMR-1. WBPaper00005972
Added WBGene ID of HMR-1 to Column 16.
Molecular Function Examples:
Nucleic Acid Binding
Example 1: sup-26 is annotated to GO:0003730, mRNA 3'-UTR binding. The entry in Column 16 is the target of that binding, tra-2.
In OA entry: Column 16: WB:WBGene00006605
Cellular Component Examples:
So far, there are three types of extensions added to Cellular Component annotations:
- part_of(Anatomy_term) http://wiki.geneontology.org/index.php/Annotation_Extension_Relation:part_of
- exists_during(Lifestage) http://wiki.geneontology.org/index.php/Annotation_Extension_Relation:exists_during
- exists_during(GO Biological Process) http://wiki.geneontology.org/index.php/Annotation_Extension_Relation:exists_during
Plans/Projects in progress
- The GO annotation model is becomingly increasingly complex, capturing more annotation detail.
- The proposed model below would create a ?GO_annotation class that includes tags for the following GO fields:
- GO_code: the evidence code used for making the GO inference
- Gene_rel: captures the explicit relation between a GO term and the gene product annotated, including 'NOT' relations
- Annotation_made_with: entities captured in the GAF With/From column for populating identifiers used with certain GO codes such as IPI (Inferred from Physical Interaction), IGI (Inferred from Genetic Interaction), IC (Inferred from Curator), etc.
- Annotation _extension: for capturing annotation context using additional ontologies or entities. Entries in the annotation extension column could be used to help construct the LEGO models of pathways and processes (see http://wiki.geneontology.org/index.php/LEGO_Model_Draft_Specification).
- Annotation_isoform: used in cases where an experiment describes the activity of a specific protein isoform; currently this information is captured with a UniProtKB accession; we would like to convert these to WB WP IDs. See tra-1 annotations for an example.
- Interacting_strain and Interacting_species: for capturing the strain or species when dual-taxon GO annotations are made, for example, to annotate gene products involved in host-pathogen interactions.
- Reference: if a published paper is used as evidence.
- GO_reference: to capture GO_REF IDs for annotations that do not cite a published paper, but rather a documented GO curation practice (used for ND annotations, for example see GO References
- Contributed_by: Uses ?Analysis objects to incorporate GO annotations from other annotation groups such as the PAINT curation efforts, UniProt, IntAct, etc. with proper attribution for the annotation source.

Since we are now sharing a GO curation tool with UniProt, in the annotation file we get back from them, we will have isoforms listed as Q9N5D6-2 and would like to be able to map them back to a specific WP: identifier.

Expanded IEP Evidence Code
What kinds of experiments are used to inform selection of the IEP evidence code?
- WBPaper00006024|PMID:12869585 - Figure 2E and 2F illustrate promoter reporter fusions showing increased expression under different stress conditions. This type of experiment assays promoter activity.
- Possible evidence code: ECO:0000296 green fluorescent protein transcript localization evidence
- Possible new evidence code: ECO:new green fluorescent protein transcript localization evidence used in manual assertion
- WBPaper00006024|PMID:12869585 - Figure 5F and 5G illustrate a translational fusion showing increased expression under different stress conditions. The time frame of the response suggests that this is a posttranscriptional event, possibly the protein moving from the cytoplasm to the nucleus.
- Possible evidence code: ECO:0000300 green fluorescent protein immunolocalization evidence
- Possible new evidence code: ECO:new green fluorescent protein immunolocalization evidence used in manual assertion
- WBPaper00026814|PMID:16166371 - Figure 1A. Experiment measures an increase in the modified (i.e., phosphorylated) form of PMK-1 in response to treatment with several different oxidative stresses, e.g., sodium aresenite, paraquat (superoxide), and t-butyl peroxide (hydrogen peroxide).

Platinum Gene Lists
Papers that use C. elegans GO Annotations
- The resulting fold-changes and p-values were then used for GOMiner  and Cytoscape [37,38] analyses.
- Detailed descriptions of GOMiner and Cytoscape analyses are accessible as Supplemental methods.
- Detailed GOMiner and Cytoscape (jActiveModules and BiNGO) analyses of strain-to-strain differences under both UV and control conditions can be found in Supplemental data files 2–5 (GOMiner) and 6–7 (BiNGO).
- Differentially expressed transcripts (defined as absolute fold change value > 1.3, a log ratio p-value < 0.05 by Rosetta Resolver, and a log(10) intensity measurement > −0.4) along with fold-change, p-values and GO annotation are listed for each strain and year in Supplemental data file 8.
- 3.9. Gene ontology (GO) biological processes altered 3 h post-UVC exposure
- Since our list of UVC-regulated genes based on a minimal 1.3-fold change was relatively short (Table 1), we also carried out a jActiveModules network analysis. This algorithm can identify subnetworks highly enriched in regulated genes even if the fold-changes are not large, since it is based only on p-values .

- WBPaper00040880 - The 662 genes associated with the modification of 128Q-neuron dysfunction appeared to encompass a variety of biological processes (cell death, protein folding, intracellular transport, metabolic processes, response to stress, stress-activated pathways) that may have a role in neurodegenerative disease pathogenesis as suggested by their functional classification using GO annotations (Figure 3, Additional file 7: Tables S6; Additional file 8: Table S7).
- GO enrichment tests were performed using Ontologizer v2.0.
- Bauer S, Grossmann S, Vingron M, Robinson PN : Ontologizer 2.0--a multifunctional tool for GO term enrichment analysis and data exploration.
- In this respect, the network-boosted data analysis of our RNAi dataset was more instructive compared to the sole use of GO annotations or gene set enrichment analysis.
- WBPaper00040896 - Supplementary Table 2
- Enriched GO groups were defined using the Generanker tool in the Genomatix Genome Analyzer software (http://www.genomatix.de/en/produkte/genomatix-genome-analyzer.html).
- To identify pathways and molecular functions common to the genes observed by microarray analysis, we employed the gene ontology (GO) enrichment analysis using GOrilla . As expected due to NHR-49’s known role in lipid biology, there was a significant overrepresentation of GO-terms for functions related to fat metabolism (Figure 2 and Table 2). We also found that pathways regulating protein processing, maturation and proteolysis were overrepresented.
- Figure 2. Functional classification summary for the nhr-49 mutant are represented as a scatter plot using the GO visualization tool REViGO.
- Gene ontology (GO) enrichment analysis was performed using GOrilla . Each list from the limma analysis was ranked from smallest to largest p-value and analyzed for enriched biological process ontology terms found near the top of the list. Functional classification summary for the nhr-49 mutant were presented as a scatter plot using the GO visualization tool REViGO .

- Gene ontology classification was acquired using the Database for Annotation, Visualization, and Integrated Discovery (DAVID, http://david.abcc.ncifcrf.gov/).
- DAVID identified many biological themes among our list of STAU-1 targets. These included embryonic, larval, and reproductive development (Fig. 5B and Supplemental Dataset 1). These are consistent with Staufen’s previously characterized role in developmental patterning in Drosophila oocytes and embryos (32,33,62).
- In addition, major GO terms associated with the human Staufen targets include cellular metabolism and cellular processes (42), and are not similar to the GO terms associated with C. elegans STAU-1 targets. We note that our studies analyzed STAU-1- associated RNAs in whole animals containing a wide array of cell types, whereas the human proteins were analyzed in a cultured cell line. Thus the biological meaning of the apparent differences in the targets of the human and worm proteins is uncertain.
- We used the Database for Annotation, Visualization and Integrated Discovery (DAVID), version 6.7, to cluster related target genes based on enriched Gene Ontology (GO) terms [39,40]

- We then used the DAVID functional annotation program to identify biologic themes within the common up‐ and down‐regulated genes.
