WormBase Summary, December 2012
WormBase has two main tasks. One is to work on Aim 4 (Common Annotation Framework), which is described under Software Group. The second is annotation. Most of our efforts over the past year were directed towards software development; remaining efforts were focused on annotation.

Methods and strategies for annotation
Curation of the primary literature continues to be the major focus of our manual annotation efforts.
Semi-automated curation using the Textpresso information retrieval system
We also routinely employ the Textpresso information retrieval system for semi-automated curation of GO Cellular Component and Molecular Function annotations.
Computational annotation strategies:
Our computational annotation strategies include mapping genes to GO terms using InterPro domains, and mapping genes to an 'integral to plasma membrane' term based on TMHMM profiling. These methods are performed automatically as part of the WormBase database build.
Priorities for annotation
Selection of genes for annotation was guided by several criteria:
- Publication of newly characterized genes
- C. elegans genes orthologous to human disease genes
- Genes identified in the Textpresso-based curation pipelines
- Re-annotation of genes associated with now obsolete GO terms
- Annotation of gene sets involved in specific biological processes as part of a pilot project on LEGO-style annotation
- Engulfment of apoptotic cell and phagosome maturation involved in apoptotic cell clearance
- Regulation of development, heterochronic
- Innate immune response
- Wnt receptor signaling pathway, regulating spindle orientation
- Determination of L/R asymmetry in nervous system
- Oocyte maturation
- Sex determination and dosage compensation
- Vulval development

Ontology Development Contributions
WormBase continues to contribute to ontology development through creation and definition of new GO terms as well as revision of existing terms.
New term requests included:
- nematode larval development, heterochronic
- regulation of nematode larval development, heterochronic
- transforming growth factor receptor signaling pathway involved in multicellular organism growth
- insulin receptor signaling pathway involved in determination of adult lifespan
- positive, negative regulation of oviposition
- pairing center
- muscle projection, muscle projection membrane (narrow synonyms: myopodia, muscle arm)
- regulation of synaptic plasticity by receptor localization to synapse
- regulation of basement membrane organization
- regulation of RNA interference
- regulation, positive, negative of oocyte maturation
- incorrect InterPro2GO mapping for IPR003131
- double-stranded DNA-dependent ATPase activity
- new representation of tail tip morphogenesis
- synonym for nuclear inner membrane
- change definition of apical junction complex
- regulation, positive, negative of serine-type endopeptidase activity
- regulation, positive, negative of neuromuscular synaptic transmission
Annotation Outreach and User Advocacy Efforts
Ranjana Kishore is working on evaluation of website usability.
Kimberly Van Auken serves on the GO helpdesk rotation.
Common Annotation Tool (GO-CAT)
Kimberly Van Auken is developing GO-CAT.
In June, Caltech hosted a small, working group meeting consisting of Suzi Lewis, Chris Mungall, and Heiko Dietze (LBL), Tony Sawford (EBI), Paul Thomas (USC), and Paul Sternberg, Hans Michael Mueller, Kimberly Van Auken, and Juancarlos Chan (Caltech). The meeting discussed the feasibility of using the Protein2GO annotation tool as a common annotation tool and strategies for migration of curation groups to Protein2GO. Other work from this meeting focused on implementing additional validation checks in the Protein2GO tool and modeling LEGO-style annotations.
Please see the Software Working Group report for a more detailed discussion of the CAT development.
Ranjana Kishore particpated in the PAINT training workshop at Stanford in December 2012.
Column 16 Annotation Extension
WormBase has begun populating Column 16, the Annotation Extension column, for a number of annotations. Data captured in Column 16 include Cell and Tissue Type using the Worm Anatomy Ontology, targets of regulation using WormBase gene IDs, and enzymatic substrates, also using WormBase gene IDs.
Gene Ontology Consortium Meeting
Caltech hosted the GOC meeting in October 2012.
