WormBase Summary, December 2012

Overview

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.

Staff:

  • Juancarlos Chan, software developer
  • Ranjana Kishore, curator
  • Kimberly Van Auken, curator

Textpresso

  • Hans Michael Mueller, PI
  • James Done, software developer

Methods and strategies for annotation

Literature curation:

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 pipeline
  • 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
